Summary [WebXR][OpenXR] Add EGL fences for WebGL content

Currently there is no guarantee that the WebXR WebGL frames are completely rendered before they're submitted to the OpenXR compositor. That's why the WebXROpaqueFramebuffer does a glFinish() before returning from endFrame. It'd be however much better to just create a fence, export it to the UI process and let it wait for the fence signaling if required instead of blocking the WP in the glFinish() call.
