Revert of [Mac] Use a native MessagePump instead of a MessagePumpDefault (https://codereview.chromium.org/331513002/)
Reason for revert:
Broke Jingle unit tests on the bots.
Original issue's description:
> [Mac] Use a native MessagePump instead of a MessagePumpDefault
>
> Many message loops in Chrome are backed by MessagePumpDefault which uses a WaitableEvent object to sleep, this is ultimately implemented as a pthread condition variable on POSIX.
>
> In order to support timer coalescing in MessageLoops we need to sleep using a primitive which supports timer coalescing at the OS level (support for timer coalescing goes down into the kernel on Android/Linux/OSX/Win). The current change achieves this and should provide a way to gauge the effect of timer coalescing.
>
> An alternate approach to this patch would be to implement MessagePumpDefault using a primitive which supports timer coalescing.
>
> Local performance tests didn't uncover any regressions from this change.
>
> BUG=356804
