[Apple M1] Nimbus add support for M1 debugger break

BEGIN_PUBLIC add support for arm macOS devices debugger breakpoint

* Fix for jumping into debugger on M1 device with Simulator

END_PUBLIC

Tested if __builtin_debugtrap(); was working correctly
by adding it to my project on M1 MacbookPro and when hitting
that function in my App, it worked as expected by jumping
in the debugger and then also able to continue the app
after this.
