Re-land "Move rounded corner to provider"

Move rounded corners code from ScreenDecorations.
1. Move business logic to RoundedCornerDecorProviderFactory.
2. Move view and inflating into RounedCornerDecorProviderImpl.

Previous landed CL: ag/17154523
Previous reverted CL: ag/17350408

Bug: 218951516
Test: atest RoundedCornerResDelegateTest ScreenDecorationsTest \
      RoundedCornerDecorProviderFactoryTest OverlayWindowTest \
      PrivacyDotDecorProviderFactoryTest
Test: Manually testing rounded corner when display size, rotation
      changed on normal devices, foldable devices, and hardware-overlay
      devices
