Fix some bugs and add hint on input filed

1. Fix talk back click "No items" crash:
   Do not handle message holder click event.

2. Fix input field background shift bug:
   Because input field have background after MDC lib updated,
   it should use margin instead of padding to ensure background
   position.

3. Fix button not visible bug:
   MDC lib use colorPrimary as text color default, update
   colorPrimary different from colorBackground, and use colorBackground
   to layout background default.

4. Update alertDialog to androidx version to remain text button style.
5. Add hint on input field when rename and new folder.
