Log Message

Add ENABLE_UI_SIDE_COMPOSITING and use it in a few places
https://bugs.webkit.org/show_bug.cgi?id=205982

Reviewed by Jon Lee.
Source/WebKit:

All Remote* things should get wrapped in ENABLE(UI_SIDE_COMPOSITING)
if other platforms build the files, so do some of that. VisibleContentRect*
and ViewUpdateDispatcher* stuff is also UI-side compositing only.

Source/WTF:

Add a #define ENABLE_UI_SIDE_COMPOSITING for Cocoa platforms. Minor comment cleanup, and
move the duplicate ENABLE_ASYNC_SCROLLING from iOS and macOS sections into the Cocoa section.
