Add a system trace scope for event region building
https://bugs.webkit.org/show_bug.cgi?id=195226

Reviewed by Jon Lee.

This trace scope measures the time spend converting element rects into Region objects,
which can be large on some pages.

The value for "Display Refresh Dispatch to main thread" was wrong and I fixed it.
