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.
