Webxrdevice (#2000)
* crates/web-sys/webidls/enabled/WebXRDevice.webidl * Add WebXR Web IDL. * Add WebXr example. * Workaround in WebXR for FrozenArray and XRWebGLLayer constructor. * Remove commented code. * Attempt to improve WebXr example. * Add WebXr as unstable WebIDL. * Fixes for XRWebGLLayer. * Tidy up WebXR example code. * Update WebXr example docs. Co-authored-by: Kev Kirkland <kev.kirkland@elucidata.co.uk>
