  [WebXR] Remove use of WeakPtr in PlatformXRCompositor
https://bugs.webkit.org/show_bug.cgi?id=313948
rdar://175742141

Reviewed by Chris Dumez.

CompositorCoordinator is a LazyNeverDestroyed singleton, so
WeakPtr<CompositorCoordinator> is unnecessary. Add a static `singleton()` getter
and replace WeakPtr{*this} captures in callbacks with plain `this`
captures. Remove `CanMakeWeakPtr` and the deprecated exception.

Also replace WTF_DEPRECATED_MAKE_FAST_ALLOCATED with WTF_MAKE_TZONE_ALLOCATED,
and fix the startSession callback to properly promote WeakPtr<WebPageProxy> to
RefPtr.
