Explicitly set max_pending_frames = 1 for renderer output surfaces.

All configurations of CompositorOutputSurface have max_pending_frames
set to 1 but it's hard to see that unless you look at all of it's
subclasses. In particular both MailboxOutputSurface and
DelegatedCompositorOutputSurface set max_pending_frames to 1 and so does
the CompositorOutputSurface when using a SoftwareDevice. These are all
the configurations of CompositorOutputSurface that exist.
