  [WebXR] Use ANGLE extension to signal compositor completion event
https://bugs.webkit.org/show_bug.cgi?id=246589
rdar://problem/101212895

Reviewed by Dean Jackson.

Use MTLSharedEvent, provided by WebXR system compositor, that signals when scene
rendering is completed using the EGL_ANGLE_metal_shared_event_sync extension.

To enable, set USE_MTLSHAREDEVENT_FOR_XR_FRAME_COMPLETION to 1
