TestSharedContextVBOES2NEWT5: Try harder having the objects destroyed and taken from the GLContextShareSet map

The objects were more sticky on my MacOS 12 x86_64 machine, this double GC w/ sleep 100ms resolved it.

JAWTWindow.invalidateNative() and .detachSurfaceLayerImpl(): Pass copy of offscreenSurfaceLayer for pending off-thread operation and immediately zero reference marking its future destruction.

JAWTWindow.ctor: Initialize offscreenSurfaceLayer before use

MacOSXCGLContext.AttachGLLayerCmd: Allow DetachGLLayerCmd to revoke the attach command, essential if attach hasn't been done yet @ detach

Otherwise a pending attach would still pass through after DetachGLLayerCmd releases the sync-lock from AttachGLCmd.

DetachGLCmd also tests 0 != nsOpenGLLayer

OSXMisc.m: Show semantics: caLayer -> rootCALayer

MacOS: JAWTWindow.layoutSurfaceLayerImpl(): Perform OSXUtil.FixCALayerLayout() on main thread and hence fetch and validate getAttachedSurfaceLayer() when needed

MacOS: JAWTWindow's OffscreeLayer: Show semantics in argument names and complete null checks in detachSurfaceLayerImpl(), setSurfaceScale()

MacOS: JAWTWindow.invalidateNative(): Use copied references in off-thread operations and zero source references upfront.

Have user being aware of disposal then triggered and not later when performed on MacOS main-thread

MacOS: JAWTWindow: Complete MacOS 12+ SIGSEGV JAW Crash Fix; This: Destroy NSWindow on MacOS main-thread

Destroy NSWindow on MacOS main-thread, avoiding spurious more rare SIGSEGV on MacOS 13/aarch64

This closes the MacOS 12+ SIGSEGV JAWT (CALayer) crash fix, see commits:

Minor auto formatting: @Override, ..

Test MouseAdapter: Use volatile qualifier to avoid reading too old values

AWTRobot.getClickTimeout(): NEWT Case: Return maximum(AWT, NEWT), otherwise we see click-count 2 on MacOS 12

scripts/tests*.sh: Put 'ulimit -c unlimited' in root script

Add scripts/run-test-until-crash.sh: Used to stress test one unit test (for sporadic crashes)

Workaround MacOS + SWT 4.26: java.lang.NullPointerException: Cannot invoke "org.eclipse.swt.internal.cocoa.NSGraphicsContext.saveGraphicsState()" because "context" is null

On MacOS 12+ and SWT 4.26 while not using AWT (-Djava.awt.headless=true, -XstartOnFirstThread),
we recently get the following Exception from SWT (suppressed):

jogl's Debug.class: Add explicit debugNotAll(..) variant to skip debugAll()

MacOSXCGLContext: Enable DEBUG1398 explicitly w/o debugAll()

MacOSXCGLContext: Fix typo in DEBUG output

build-test.xml junit.run.swt.awt: Add missing 'jvmarg.generic'

SWTAccessor.invokeOnOSTKThread(): Fix comment ..
