Establish Connection Between XR and GPU Process
This CL establishes a connection between the XR and GPU processes when the XR process gets created for the OpenXR runtime. Context lost callbacks from viz::ContextProvider are handled by recreating the GPU process connection. A future change will use the connection to open a shared image for the WebXR backbuffer. The shared image will allow the GPU process to render directly into the XR backbuffer and avoid the copy + flip operation we perform today.
