[WebXR|visionOS] Try shared MTLTexture before falling back to IOSurface
https://bugs.webkit.org/show_bug.cgi?id=316380
rdar://178666073
Reviewed by Mike Wyrzykowski.
When entering immersive VR mode on visionOS simulator only black is rendered
because the compositor surfaces passed as IOSurfaces return 0x0 dimensions.
To fix this, we know use the same logic as a visionOS device. Try to access the
compositor surfaces as shared MTLTextures before falling back to trying
IOSurface.
Tested by launching Safari in simulator and trying a WebXR immersive VR page.
