WebVR: use optimized render path with deferred wait

WebVR: use optimized render path with deferred wait

Now that the synchronization issue (occasional black screen flashes) that
affected the optimized render path is fixed (see issue 723962 and
crrev.com/2891033002 / r473687), switch to that implementation and
remove the old code path.
