- 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
