Bug 1398: Crash only occurs @ -[NSOpenGLContext setView:] when using XCode 11 _and_ its default SDK 'macosx10.15'

This patch demonstrates that using the SDK 'macosx10.11' does not cause the crash @ -[NSOpenGLContext setView:].

SDK 'macosx10.15' enforces Apple's own Cargo Cult of 'main-thread' by throwing a SIGILL signal (or SIGABRT)
- essentially an exception.

This surely renders our code officially invalid due to this policy,
i.e. we are not allowed to issue [* setView] on any non main-thread.

+++

The crash occurs independently of used Java version on Java 8 - 11,
as well as on JogAmp 2.3.2 - current master tip.

+++

The initial remedy to issue said action on the main-thread in a blocking/wait
manner has the risk to deadlock, due to

1) [NSOpenGLContext setView:] itself using a mutex (Thanks to Ken Harris's analysis)

and

(2) in case where we are 'thread hopping':
- [main-thread] Event like 'window ready' -> kick off action on EDT-thread *blocking*
- [EDT-thread] Create stuff incl OpenGLContext -> kick off setView on main-thread *blocking*

This has to be further investigated.

This crash finally has been reliably reproduced now.
