mus-ws: Plumb FrameSinkId to Children
This CL takes us a step closer to surface synchronization by plumbing the
correct FrameSinkId to children and delaying CompositorFrameSink creation
until the FrameSinkId is propagated to the child.
FrameSinkIds are plumbed to children via:
1. WindowTreeClient::OnTopLevelCreated
-- for top level windows like Chrome
2. WindowTreeClient::OnEmbed
-- for embedded apps and OOPIFs
3. WindowManager::WmNewDisplayAdded
-- for the window manager's CompositorFrameSink
Requesting a CompositorFrameSink from WindowPortMus is now async,
and completes when the FrameSinkId is available.
