Removing the Paste as plaintext option from the insert and selection context menu

[fabOnReact]

Summary:

Remove Paste as plaintext from Android EditText context menu.
Related PR Over-riding onTextContextMenuItem in ReactEditText to copy/paste plain text instead of rich-text #38189.

What is the root cause of that problem?

Android EditText and iOS UITextField/UITextView have different copy/paste behavior.

• Android TextInput copies/pastes rich text
• iOS UITextField copies/pastes plain text.

What changes do you think we should make in order to solve the problem?

The issue is a bug in react-native #31442:

1. The JavaScript TextInput and ReactEditText Android state are not in sync
2. The TextInput Android Native state over-rides the JavaScript state.
3. onChangeText passes a plain text string to JavaScript, not rich text (text with spans and styles).
