feat: New Sample App

[homuler]

Fix #165, #219, #242, #244, #245, #253, #276
Close #27, #111, #131, #192, #237, #239, #249

I have rewritten the sample app.
Major changes are as follows:

Features

• Support Objectron on iOS, Linux CPU, macOS, and Windows
• Support InstantMotionTracking on iOS, Linux CPU, macOS, and Windows
• Support HairSegmentation on iOS, macOS, and Windows
• Support BoxTracking on Windows
• Enable to use image or video as the input
• CalculatorGraph#AddOutputStreamPoller now supports observeTimeoutBounds
  • We don't need to check if the next output exists by using PacketPresenceCalculator any more.

Performance Improvements

• Get output values asynchronously by default
• Timeout time can now be set when the graph runs asynchronously

Bug Fixes

• Annotations aren't correct when the input image is rotated
• Depending on the orientation of the device, the orientation of the image may not be correct
• Stop WebCamTexture when a scene is exiting
• Crashes when calling CalculatorGraph#ObserveOutputStream with an invalid stream name
• Protobuf logger causes crash randomly

Miscellaneous

• Glog will output logs to standard error (or Editor.log) by default
• Glog's log options can be set from UI
• Model files (e.g. *.tflite) are included to the app as StreamingAssets by default (AssetBundle is optional now)
• Enable to configure annotations from Inspector Windows in Play mode
