[WebXR] Display WebGL content over camera feed
https://bugs.webkit.org/show_bug.cgi?id=262774
rdar://116502727
Reviewed by Dean Jackson.
WebGL content compositing is implemented by creating a CAMetalLayer sublayer
positioned on top of the CALayer containing the captured camera
image. MTLSharedTexture and MTLSharedEvents are passed via MachSendRight to
WebXROpaqueFramebuffer, which passes those objects to the process that handles
WebGL rendering. Presentation of the WebGL content and associated camera images
is fenced on the signalling of the MTLSharedEvent passed to WebGL.
