Fix 2402303: Split Keyboard widget from LatinIME into reusable PasswordEntryKeyboardView
- Added new PasswordEntryKeyboardView to internal/widgets. Widget supports:
- alpha mode with symbols (latin-1 only).
- a numeric keyboard
- IME emulation that applies keyboard input to arbitrary top-level view widget.
- Added new transparent assets to framework resources.
- Modified Keyguard and Keyguard layouts to use new PasswordEntryKeyboardView.
