Godot OpenXR Vendor plugin version 4.0.0-stable changed the plugin's manifest declaration, so this updates the logic to remove that manifest declaration to match.
- Only request the permission the first time the editor tries to open an apk
- Disable the permission for the HorizonOS build as the HorizonOS store doesn't support it yet
A few permissions including the `USE_SCENE` permission are being renamed with the launch of the Meta Spatial SDK, so we update the excluded list to avoid requesting them on app start.
