Summary:
On Android, if there is a small amount of space available around a text input (e.g. landscape orientation on a phone), Android may choose to have the user edit the text inside of a full screen text input mode. This behavior isn't always desirable. For example, if your app offers some UI controls for controlling the formatting of the text, you want the controls to be visible while the user is editing the text. This Android feature conflicts with that desired experience because the UI controls would be hidden while the text is being edited.
The `disableExtractUI` prop enables developers to choose whether or not Android's full screen text input editing mode is enabled. When this prop is true, Android's `IME_FLAG_NO_EXTRACT_UI` flag is passed to the `setImeOptions` method.
**Test plan (required)**
Verified `disableExtractUI` works for both `true` and `false` values in a test app.
My team is also using this change in our app.
