Alex Chau 557d8e6d7f Reland "Recreate Launcher activity when blur enabled changes" ...

- When battery saver changes, WallpaperThemeManager always recreate activity to reapply theme base on wallpaper color hint changes
- Battery saver change can also result in light/dark theme changes, for which WallpaperThemeManager also recreate activity to apply theme changes
- As a result, it'll be much simpler to recreate activity whenever isBlurEnabled changes
- Exposed recreateToUpdateTheme API from WallpaperThemeManager to achieved this
- Greatly simplified Overview styling to read from styles

Reland fix:
- Removed mBlursEnabled in BaseDepthController, and only use `mCrossWindowBlursEnabled` to control swapping between blur style and fallback style
- Temporary variables like `mPauseBlurs` and `hasOpaqueBg` should only affect if blurs are applied, but not result in swapping of blur style, otherwise this cause unnecessary redraw or activity recreate
