fix display cutout / notch support

[wangcheng]

currently the support for notch is broken. mainly because we didn't reassign layoutParams to the view so the new params won't apply.

to solved this. I rewritten the logic and improve the notch handling.

• fixed the bug that layoutParams is not reassigned
• toolbar's background is expanded under the notch area.
• always set seekbarCard width to 50% (no matter the OS version) to make room for moveBtnContainer
• handles display cutout from every direction
• changed some layout attributes
  • removed seekbarCard vertical margin in landscape mode because we are setting its width 50% anyway.
  • added a marginBottom to seekbarCard.
  • changed moveBtnContainer marginEnd to marginRight because we are setting marginRight in the code and marginRight and marginEnd cannot be set at the same time. I also ignored the RtlHardcoded warning because this won't really break RTL support.

I test some scenarios with notch emulation in the developers options menu.
