  [UI-side compositing] Add logging for painting new tile for ScrollPerf
https://bugs.webkit.org/show_bug.cgi?id=254050
rdar://106775893

Reviewed by Simon Fraser.

Use iOS's RemoteLayerTreeScrollingPerformanceData to calculate blank tiles
for new tile creation and scrolling. Log all of the accumulated log events
when the WebPageProxy is closed. Also, disable the logging on TileController
to prevent double logging new tile events in the web process by having
PlatformCALayerRemoteTiledBacking set a bool.
