Details | Review 
When multiprocess is enabled on Android (Firefox Reality) there are some SurfaceTexture errors. This happens because the WebGL textures used in WebVR are not detached correctly from Gecko thread, and can't be used in the VR render thread.

Also there is a race condition where WebGLContext::GetVRFrame can be called multiple times before a VR frame is fully processed. SurfaceTextures need to be released from the Firefox Reality render thread in order to allow be used again in the WebGLContext producer. Not doing this causes some freezes, crashes or other undefined behaviour.

status-firefox62=wontfix. We don't need to uplift this fix to GeckoView 62 Beta because FxR will ship with GeckoView 63.
