DevTools Timeline: expose HitTest event

DevTools Timeline: expose HitTest event

This renames LayoutView::hitTest trace event to HitTest and exposes it
in Timeline. Also, event data builder is moved to IsnpectorTraceEvents
and changed to match field names used through other timeline trace events.

"LayoutView::hitTest", "info", hitTestInfo(request, location, result));
Is there a special handling of the info param that needs to be updated in trace
viewer?
