Summary:**Problem**: As seen in facebook#5820, many devs are confused by the fact that the offline bundle is not generated when running against the simulator, even when running in the "Release" configuration which is supposed to mimic "production" scenarios.

This pull request is a small change that fixes facebook#5820 by updating the `react-native-xcode.sh` shell script to still generate the ofline bundle during Release configuration. It also updates `AppDelegate.m` to better document this behaviour in the comments so as to avoid any surprises.

**Test plan**: This is a simple change, the two tests done were
1. In a new React Native project, verify that an offline build is not generated when running against the simulator in "Debug" configuration as per normal.
2. Change to a "Release" configuration via Product > Scheme > Edit Scheme in XCode, then verify that the project runs with the offline build generated.

Summary:Hello!

As described in facebook#3288, the `PushNotificationsIOS` `register` callback fires twice.  See that issue for discussion.

There wasn't any feedback on a proposed PR, so this is the first effort.  This change does make the register callback act as expected on my device.  I can make any changes necessary.

Thanks!

**Test plan**

- Run UIExplorer on iOS and Android devices

[Android]
- Go to Touchable* examples and scroll down to the `Disabled Touchable*` section. There are two new buttons there: `Enabled TouchableNativeFeedback` and `Disabled TouchableNativeFeedback`. Buttons should behave according their titles.

[iOS]
- Go to Touchable* examples and scroll down to the `Disabled Touchable*` section. As far as `TouchableNativeFeedback` is supported on Android only, you **wouldn't see** any new buttons there

Summary:Unfortunately the 'screen' option in the `UIManager.takeSnapshot` API appears to work only on the iOS simulator, not on an actual device.

This diff removes the 'screen' option until a solution can be found that works on the device.

(Taking a snapshot of the window still works fine - it just won't include the status bar, etc.)

```js
import { Component } from 'react-native';

class MyText extends Component<void, {text: string}, void> {
  render() { return <Text>{this.props.text}</Text> }

// Correctly throws a Flow error for the missing "text" prop

Summary:Geolocation timestamp is different for Android and iOs. For Android it is returning in UTC time in milliseconds since January 1, 1970, for iOS it was returned as time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001). Also for iOS time returned was "current system absolute time" and not the time at which this location was determined.

Tested with 0.21.0-rc React Native. Init project with this additional code:
`constructor(props) {super(props);
    navigator.geolocation.getCurrentPosition(
      (position) => {
        let initialPosition = JSON.stringify(position);
        console.log(position.timestamp);
      },
      (error) => alert(error.message),
      {enableHighAccuracy: true, timeout: 20000, maximumAge: 1000} );
  }
`

Summary:**Motivation**
Multiple instances of `Text` inside a `ListView` is a bad idea for the performance of the app.
When you create 1000 elements and you scroll through the list it is really slow and laggy because the `NSTextStorage`, which is the backbone of the `RCTText` element, will set more than 1,000 times and also the method `setNeedsDisplay` is called multiple times. This will causes huge memory problems and the app crashes.

With this commit I check in `RCTText` if the `NSTextStorage` differs from the old value. If yes then set it otherwise don't set the `NSTextStorage`. This will prevent to call `setNeedsDisplay` when not really needed.

Summary:Everything wrapped in `<Incremental>` is rendered sequentially via `InteractionManager`.
The `onDone` callback is called when all descendent incremental components have
finished rendering, used by `<IncrementalPresenter>` to make the story visible all at once
instead of the parts popping in randomly.

This includes an example that demonstrates streaming rendering and the use of
`<IncrementalPresenter>`.  Pressing down pauses rendering and you can see the
`TouchableOpacity` animation runs smoothly.  Video:

Ideally this will be baked into React Core at some point, but according to jordwalke that's
going to require a major refactoring and take a long time, so going with this for now.

Summary:**Motivation**

AppStateIOS never currently returns `inactive` as a possible state. I had a requirement that when inactive, certain portions of the app should be blacked out in accordance with compliance rules. This is not possible currently, due to `inactive` never being returned. This PR fixes that.

All base tests are passing. Are there AppState specific tests in place at the moment that I'm missing?

…to match Android

Summary:
## Overview

This diff switches the RCTSlider onSlidingComplete event on iOS from a bubbling event to a direct (non-bubbling) event to match the non-bubbling type on android.

Note that in this case these seems like a bug. I will still explain the motivation and reasoning as this will come up in future diffs.

## Changelog
[Slider][BREAKING] Switch Slider onSlidingComplete event to a non-bubbling event on iOS to match Android

## Motivation:

The motivation here is that when we codgen the view configs, we'll need to unify all of the events and props across platforms for components that have the same name on iOS and Android.

In this case, the view configs (below) conflict for onSlidingComplete. On iOS this is under bubblingEventTypes, on Android this is under directEventTypes. We have code [here](https://fburl.com/3s1dahm2) in the react native renderer which ensures an event is not listed as both.

```
// iOS
const SliderViewConfig = {
  bubblingEventTypes: {
    onSlidingComplete: {
      phasedRegistrationNames: {
        captured: 'onChangeCapture',
        bubbled: 'onChange'
      }

## Solutions
There are three solutions to this issue:
1. Don't generate view configs
2. Rename the component on one platform
3. Make a breaking change in the event behavior on one platform to make it consistent across both platforms

Here we've chosen option #3

Summary:
This diff allows specifying the preemptive compilation threshold via CompileFlags.
Users get a toggle in CLI and RuntimeConfig that allows choosing between 1. fully eager, 2. fully lazy, 3. use default thresholds ("smart"). The default is #3.

However, since we use `-O` by default, it overrides any lazy compilation when
using the `hermes` binary.

ChangeLog: [Internal] Inspector updated to use new RuntimeConfig laziness control

Summary:
This fix is still a little hypothetical. We have a few different JS errors that we're seeing with bridgeless mode that seem to be caused by Fabric trying to access `__fbBatchedBridge` from C++. I think what's happening is:

1. User encounters an unrelated JS error very early in rendering a new surface (possibly while the bundle is still loading?)
2. In release builds, BridgelessReactFragment handles the error by stopping the surface and rendering a retry button (actually, the surface is stopped in a bunch of places in BaseFbReactFragment, which might be why this is popping up now - I recently refactored that class to share more of its logic in bridgeless mode)
3. Fabric stops the surface by first checking to see if the custom binding `RN$stopSurface` exists; if not, it falls back to calling the registered callable module `ReactFabric`.

I think #3 is where things are going wrong for bridgeless mode; if you call stopSurface before `RN$stopSurface` is installed (which happens when ReactFabric shim is required) then you'll fall back to the bridge version.

My solution here is to instead rely on a flag set in C++ to determine whether we're in bridgeless mode, and then check to see if the stopSurface binding has been installed. If not, we just noop - if the ReactFabric shim hasn't been required, we probably don't actually have a React surface that needs to be stopped.

At least, that's my current theory. We'll see if this actually works.

Summary:
Previous iterations of this diff that were reverted: D30678341 (facebook@8009459), D30868627 (facebook@abd0f38).

With the power of selects, we can move the base AppleTVOS flags into the regular
base Apple flags.

While I'm here, drop the third `p` in `get_application_apppletvos_flags()` as
it's driving me insane.

Note - This puts get_visibility_option() on all Apple builds.  I believe this is
the right thing to do as everything except macOS static libraries already do it,
and it shouldn't affect binaries.

Summary:
This diff adds `overflowInset` values in RN Android. These values are used to give  an enlarged boundary of a view group that also contains all its children layout. Here is [the post](https://fb.workplace.com/groups/yogalayout/permalink/2264980363573947/) that discuss more on why this is useful. I steal the pic in that post here as TLDR:

{F687030994}

In the above case, we will get overflowInset for ViewGroup A as something like `top: 0, right: -20, bottom: -20, left: 0`.

This has been added in the [Fabric core](https://fburl.com/code/f8c5tg7b) and [in IOS](https://fburl.com/code/vkh0hpt6). In Android, since we used to ignore all event coordinates outside of a ViewGroup boundary, this is not an issue. However, that caused unregistered touch area problem and got fixed in D30104853 (facebook@e35a963), which dropped the boundary check and made the hit test algorithm in [TouchTargetHelper.java](https://fburl.com/code/dj8jiz22) worse as we now need to explore all the child node under ReactRootNode.

This perf issue is getting obvious when a view loads too many items, which matches our experience with "Hover getting slow after scrolling", "Hover getting slow after going back from PDP view", and "The saved list view (in Explore) is very fast (because it has very few components)"

To fix this issue, I added the support to `overflowInset` to RN Android by
1. Sending the `overflowInset` values from Binding.cpp in RN Android as a separate mount instruction
2. Update `IntBufferBatchMountItem.java` to read the int buffer sent over JNI, and pass the `overflowInset` values to `SurfaceMountingManager.java`
3. Creating new interface `ReactOverflowViewWithInset.java` and extending the existing `ReactOverflowView.java` usages
4. Adding implementation of getter and setter for `overflowInset` in various views
5. Update `TouchTargetHelper.java` to read the values and check boundaries before exploring ViewGroup's children

Note that in #3 I didn't change `ReactOverflowView.java` interface directly. I am concerned about backward compatibility issues in case this interface is being used in OSS. I suggest we deprecate it as we are not using it anymore in our code.
