Revert of Make SingleThreadProxy a SchedulerClient (https://codereview.chromium.org/134623005/)

Reason for revert:
Broke some layout tests

Original issue's description:
> Make SingleThreadProxy a SchedulerClient
> 
> This makes ui::Compositor no longer in charge of
> scheduling commits and draws, deferring it to cc::Scheduler.
> 
> Other compositors that use SingleThreadProxy are left calling composite
> synchronously and now pass a flag to indicate that this is their
> intention.  This patch doesn't remove synchronous composite, but now
> makes it mutually exclusive with scheduling.
> 
> BUG=329552, 287250
> 
> Committed: https://src.chromium.org/viewvc/chrome?view=rev&revision=287950
