cc: Reduce renderer_main thread priority when prefer_smoothness is set
This tracks how many compositors prefer smooth frame-rate,
and throttles/resets the main thread's priority as
appropriate. Compositors in the same process share the same
thread, so we track this count in a static int.
All thread priorities use #ifdefs for reduced risk and
easier merging. This needs to be abstracted and enabled
on other platforms (http://crbug.com/170549)
