Android: fix ClassCastException in ReactRootView.java when software keyboard is shown (#40755)

Summary:
Fixes #40754

Hi all!
We noticed that our app started to crash after bumping to RN v0.71.13, anyways after a deeper investigation we also found that the crash occurs in the latest version as well.

Crash log:
```
E  FATAL EXCEPTION: main
Process: com.nfl.fantasy.core.android.debug, PID: 6034
java.lang.ClassCastException: android.app.ContextImpl cannot be cast to android.app.Activity
at com.facebook.react.ReactRootView$CustomGlobalLayoutListener.getActivity(ReactRootView.java:926)
at com.facebook.react.ReactRootView$CustomGlobalLayoutListener.checkForKeyboardEvents(ReactRootView.java:946)
at com.facebook.react.ReactRootView$CustomGlobalLayoutListener.onGlobalLayout(ReactRootView.java:912)
at android.view.ViewTreeObserver.dispatchOnGlobalLayout(ViewTreeObserver.java:1061)
```
The code which causes ClassCastException is following [here](https://github.com/facebook/react-native/blob/ea88fbe229e1d276753ee8e118184274fc872138/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/ReactRootView.java#L864).
In this code explicit type conversion to Activity is not safe because it's not guaranteed by the compiler that context will be compatible with Activity type.
The appropriate issue [has been filed](#40754).

[ANDROID] [FIXED] - Fixed crash occurring in certain native views when keyboard events are fired.

Pull Request resolved: #40755

Test Plan:
Tested it manually with the [reference application](https://github.com/kot331107/rnCrashReproducer).  Repro steps are as follows:

- Build and run the app on Android
- Tap the button "Open Modal"
- You should see the red popup fragment to the bottom of the screen
- Tap on the text input to open software keyboard
- Expected: it should show the keyboard and no crash happens.
