feature: Update Image.getSize/getSizeWithHeaders methods to return a promise

[retyui]

Summary:

Image.getSize/getSizeWithHeaders are still working in old fashioned "callback" way

Image.getSize(uri, function success(width,height) {  }, function failure(){   } ); // undefined
Image.getSizeWithHeaders(uri, headers, function success(width,height) {  }, function failure(){   } ); // undefined

But in 2024 more developers prefer use async/await syntax for asynchronous operations

So, in this PR I added support for Promise API with backward compatibility, modern way:

Image.getSize(uri).then(({width,height}) => {    }); // Promise
Image.getSizeWithHeaders(uri, headers).then(({width,height}) => {    }); // Promise

Changelog:

[GENERAL] [ADDED] - Image.getSize/getSizeWithHeaders method returns a promise if you don't pass a success callback

Test Plan:

1. ts: New test cases added in typescript tests
2. runtime: you can create a new project and put code from this PR into the next files
   a. node_modules/react-native/Libraries/Image/Image.android.js
   b. node_modules/react-native/Libraries/Image/Image.ios.js

/rebase - this commet will rebase the PR on top of main automatically.

All these changes are JS changes only, there is no reason why the native builds should fail. Let's see if a rebase fixes CI.

the Facebook Internal - Builds & Tests job has failed, do I need to change smth? @cipolleschi

[cipolleschi]

I was looking into that. There is an internal E2E test that is failing and I need to understand why. I'll probably look into it tomorrow morning, as the day is almost over and I have another meeting coming up. :(
(it's the only test that is failing, all the other signals are green... ¯_(ツ)_/¯ )
