Split VrShellGl into a compositor and scheduler delegates
The delegates communicate through 2 channels in the android
implementation:
1. WebXrPresentationState, owned by the scheduler.
2. The public interface of VrShellGl. Ideally, this interface should
remain very small to ensure the task separation.
VrShellGl now only implements the CompositorDelegate, and it's soon to
be renamed. RenderLoop now owns the delegates.
