cocoadisplay: Fix fullscreen issues on M1 macs

Browse Source 
The OpenGL-on-Metal drivers used on these machines don't support CGLSetFullScreenOnDisplay, so we need to disable it on those machines.  This also applies when running a x86_64 app through Rosetta 2, hence the sysctlbyname check.

Furthermore, we need to set the appropriate shielding level, which need not be `NSMainMenuWindowLevel+1`.

Fixes #1316
