- Fix issue on foldable where the embedded window would obscure the main window when launching
- Fix edge-to-edge support for non-immersive apps / games
- Add edge-to-edge export option to allow non-immersive apps / games to extend edge to edge
- Regenerates the `GodotAppMainTheme` and `GodotAppSplashTheme` during Android export. Any manual changes to these styles will be cleared and replaced with default theme attributes.
- Adds a new export option `gradle_build/custom_theme_attributes` for injecting custom theme attributes directly via the export window, avoiding the need to manually modify themes.xml.
Due to limitations to the splash screen introduced in Android 12, the splash screen logic is updated to the same logic as used on other platforms, i.e: the splash screen is rendered by the Godot engine instead of the Android runtime.
In addition, add support for scaling and applying filter to the splash screen on Android.
One limitation of the api being used is that the splash screen aspect ratio is not maintained when it's scaled up.
