Compositors provide an MTLSharedEvent to be signalled at the completion of scene rendering. Now that ANGLE supports signalling external MTLSharedEvent (https://bugs.webkit.org/show_bug.cgi?id=243529), WebXROpaqueFramebuffer rendering should us this to signal when the compositor is free to start composition.
