Web Inspector: When selecting timeline records from a coalesced record bar, select the record nearest the cursor, not the first record in the group

We now attempt to find the closest possible record to the location on the timeline the record bar was clicked. If we can
provide a record that starts before and end after the point that was clicked we return that record, otherwise falling
back to the record the either started or ended closest to the point that was clicked. This should make it easier to jump
to records the represent a larger portion of time, like a slow paint, without having to zoom all the way in on the
timeline.

Records with children are not considered since the children records will be the next records checked, and we want to
have selection be as targeted as possible.
