Mus: Fix Capabilities and Install SwapBuffersCompleted/VSync callbacks

DirectOutputSurface(Ozone) should be informed when a swap buffers is
completed or when vsync parameters are updated so that it can update the
compositor accordingly. We need to make sure that the callback is called on the Mus
compositor thread. InProcessCommandBuffer calls
these callbacks on the "origin" thread in this patch.

Furthermore, InProcessContextProvider was faking Capabilities instead of grabbing
them from InProcessContextProvider. This doesn't work on
ozone platforms.
