feature: Update `Image.getSize/getSizeWithHeaders ` methods to return a promise (#42895)

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

```tsx
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:

```tsx
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

Pull Request resolved: https://github.com/facebook/react-native/pull/42895

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`
