-----------
Allow WebKit to run main-thread frames in parallel with CoreGraphics.
https://bugs.webkit.org/show_bug.cgi?id=302187
<rdar://163067859>
Reviewed by Simon Fraser.
Rather than waiting on the GPU process to finish CPU-side flushing of
CoreGraphics before allowing the next rAF to start, allow one previous frame to
still be in progress.
Use RemoteLayerTreeDrawingAreaProxy::notifyPendingCommitLayerTree to determine
when a frame has finished the WebKit main thread work, and allow sending a
second displayDidRefresh message at this time, before the previous
commitLayerTree message has been received.
