Bug 1638123 - Call WebGLContext::ClearVRFrame when ending WebXR session. r=jgilbert,kip,daoshengmu

Browse Source 
In WebVR we call WebGLContext::ClearVRFrame when the presentation ends. We didn't have the equivalent call in WebXR. It helps to reduce memory usage earlier when exiting WebXR and reduces potential deadlocks if the ExternalVR client didn't call SurfaceTexture->ReleaseTexImage() correctly.
