Revert "Reland "Unify input delay computations""

This reverts commit 4d820bcdc64f018c4ad2142ce2bfcbf1be2a0410.

Reason for revert: causes flakiness in browser_tests (907981).

> > Unify input delay computations
> >
> > This CL unifies the timestamp computations for FID as reported to UMA and FID as
> > exposed in the Web Perf API. It moves the UMA reporting from the
> > PageWidgetDelegate to the EventTiming class. After this CL, the same types of
> > events are logged by both the UMA metric and the webexposed metric. In addition,
> > this CL removes the check that there are default actions or event handlers from
> > EventTiming, which means that now the webexposed API will expose events even if
> > they have no associated event handlers. In particular, this means that a click
> > will now trigger mousedown, click, and mouseup entries, in that order. This is
> > reflected in changes to the layout tests.
