  [WebXR] Runtime reachability of WebXR IPC endpoints

Reviewed by Alex Christensen and Tim Horton.

This change uses [EnabledIf=""] attribute to enable reachability to WebXR
IPC endpoints on when WebXREnabled preference is enabled. This allows runtime
control over handling of messages, with any messages received when disabled
being dropped.
