Fix "Consecutive" Event Logs in Performance Track (#34659)

Reset EventTime when clearing timers. We need to track repeat updates
separately.

Typically we always reset all timers when we've logged an update. The
same update shouldn't be logged again.

I was trying to be clever and not reset the XEventTime because we also
need the timestamp to know if it's a repeat event. However, because of
this it looked like we had an event schedule an update even after we had
reset them.

This always resets the XEventTime to -1.1 and then stashes the old time
on EventRepeatTime which is our indication whether the next update was a
repeat of the old event.
