Decouple BrowserCompositorOutputSurface from BeginFrameSource.
This change is a part of larger effort of propagating D3D VSync
signal to the compositor. Since the current implementation in
BrowserCompositorOutputSurface explicitly depends on a time based
SyntheticBeginFrameSource, enne@ suggested that a good first step
would be to try to decouple it from a specific BeginFrameSource
type.
Instead of passing SyntheticBeginFrameSource and CompositorVSyncManager
in every constructor of BrowserCompositorOutputSurface and classes
derived from it, this change replaces the SyntheticBFS / VSyncManager
pair with a callback to update VSync parameters. The callback is
handled at GpuProcessTransportFactory.
