Add tests for AndroidForegroundService default behavior

- Introduced `UseMauiCommunityToolkitMediaElement_ShouldSetAndroidServiceByDefaultToFalse` to verify that `AndroidForegroundServiceEnabled` is `false` by default.
- Renamed `UseMauiCommunityToolkitMediaElement_ServiceCanBeDisabled` to `UseMauiCommunityToolkitMediaElement_ServiceCanBeEnabled` and updated its logic to check the service's initial state and enable it.
