[WebXR] Clamp minimum depth for PlatformXRCompositor
https://bugs.webkit.org/show_bug.cgi?id=319539
rdar://181951902
Reviewed by Mike Wyrzykowski.
The compositor can place a constraint on the minimum depth value that is
allowable for the page to render with. When breaking this constraint,
CompositorServices crashes with a debug message.
Query the minimum depth and clamp the requested range to the minimum.
Additionally, when a page tries to use reverse-Z for the depth range generate
the projection matrix using the correct convention.
Tested on visionPro with WonderLand engine example.
