Revert 213338 "cc: Allow the main thread to cancel commits"

Broke WebViewInteractiveTest.EditCommandsNoMenu on Mac

[1288:27139:0723/221703:FATAL:layer_impl.cc(286)] Check failed: TotalScrollOffset().y() <= max_scroll_offset_.y() (62 vs. 47)

> cc: Allow the main thread to cancel commits
> 
> Add a new SetNeedsUpdateLayers that triggers the commit flow, but is
> abortable if update layers doesn't actually make any changes.  This
> allows the main thread to abort a begin frame.  This happens in the case
> of scroll updates from the compositor thread or invalidations.
> 
> There was previously an abort begin frame call for when a visibility
> message and a begin frame message were posted simultaneously, but it
> incorrectly applied the scrolls and scales without informing the
> compositor thread that these had already been consumed.  To fix this,
> the abort message passes back a boolean about whether or not the
> commit was aborted (and needed to be sent again) or was handled
> (and the scrolls and scales processed).

> To avoid a deluge of begin frames (in the commit sense) from the

> frame (in the vsync signal sense) so that these calls can be throttled.
> Otherwise, the scheduler will just keep trying to begin frame.
