Add prop to filter drag and drop pasting on Android (#49446)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49446

On Android, by default, every EditText accepts `DragEvent` and will automatically focus themselves to accept these data. In some rare cases, it might not be desirable to allow data from arbitrary drag and drop events to be pasted into a text input.

This change adds a new prop `acceptDragAndDropTypes`  to do exactly that: reject drag and drop events by telling the system to ignore certain types of drag data and, by proxy, disabling behavior that automatically focuses the text input.

The prop accepts a subset of MIME types supported by Android as documented [here](https://developer.android.com/reference/android/content/ClipDescription#MIMETYPE_TEXT_HTML).

It's important to note that this is an experimental prop, as is evident by the `experimental_` prefix on the JS side. Its signature could change before the prop has fully matured, use at your own risk
