Mac: Don't draw a cc::Surface while suspended

Mac: Don't draw a cc::Surface while suspended

It is possible that, when closing a tab on Mac, the RWHVMac that
is being closed will have requested that the ui::Compositor draw, and
that draw will have not happened yet. The draw will happen after
the RWHVMac and its renderer have been destroyed which is wasteful
in that the draw is unwanted and buggy in that the resources needed
by the draw are destroyed.

To avoid this, ensure that the cc::Surface does not draw if the output
surface is suspended.

This either regressed when the ui::Compositor was moved to use the cc::Scheduler
or when it was moved to use cc::Surfaces. Either way, this makes the issue go
away (and makes closing an animating tab faster).
