Revert 202620 "Collect tab timing information for use in telemen..."

> Collect tab timing information for use in telementry-based startup tests
> 
> Motivation: Data collection exposed in this CL is needed by upcoming startup tests we're writing using Telemtry.
> 
> Expose a new window.statsCollectionController object to JS and move existing histogram reading code into it since that seemed misplaced in DOMAutomationController.
> 
> Add a new --enable-stats-collection-bindings to activate said object.
> 
> Example usage in telemtry:
> with browser.Create() as b:
>   b.tabs[0].Navigate("http://www.google.com")
>   b.tabs[0].WaitForDocumentReadyStateToBeComplete()
>   print b.tabs[0].EvaluateJavaScript('statsCollectionController.tabLoadTiming()')
> 
> BUG=None
