Revert 221427 "Add instrumentation to the MessagePumpMac family ..."
This code is no longer needed, since the experiment is not viable.
> Add instrumentation to the MessagePumpMac family of classes.
>
> This adds UMA-uploaded histograms of sampling intervals for key points of data:
> * Total time spent in a CFRunLoop
> * Total time waiting in CFRunLoop
> * Total time servicing MessagePump::Delegate (the MessageLoop)
> * The MessageLoop queue size and queueing delay before servicing
>
> It adds 1 second sampling for 15 seconds at startup, only for the main thread
> (NSApplication-based) run loops.
>
> The data will be used to determine if adding scheduling-like behavior to the
> MessagePump will result in more efficient processing of the MessageLoop work.
>
> An unforunate side effect of this change is exposing another method on the
> MessagePump::Delegate interface, but there does not appear to be a better way
> to do this.
