OSX/CALayer: Revise CALayer 'RunOnMainThread' utilization, avoiding deadlocks
RunOnMainThread(waitUntilDone:=true,..) can deadlock the main-thread if called from AWT-EDT,
since the main-thread may call back to AWT-EDT while injecting a new main-thread task.
This patch revises all RunOnMainThread CALayer usage, resulting in only one required left:
- OSXUtil.AddCASublayer() w/ waitUntilDone:=false
Hence the CALayer code has no more potential to deadlock main-thread/AWT-EDT.
OSXUtil.AddCASublayer() must be performed on main-thread, otherwise the
CALayer attachment will fail - no visible rendering result.

Note: A good trigger to test this deadlock is to magnify/zoom
the OSX desktop (click background + ctrl-mouse_wheel)
before running some unit tests.
TestGLCanvasAWTActionDeadlock01AWT and TestAddRemove02GLWindowNewtCanvasAWT
also have the potential to trigger the mentioned deadlock.
