XRDevice passes an XRSessionCreationOptions instance to WTF::Bind, and
its |output_context_| is a garbage collected object.
As we have no chance to call XRSessionCreationOptions::Trace while it's
held in the callback, |output_context_| may be collected incorrectly by
GC.

This CL expands XRSessionCreationOptions members to the parameters of
XRDevice::OnRequestSessionReturned to fix the object graph.
