    [traphandler] Add arm64 simulator support on Windows · 367f86de
    Clemens Backes authored
    This ports the trap handler implementation for the arm64 simulator
    from POSIX to Windows. Apart from different registers being used
    for passing parameters, and different access to these register
    values in the signal handler, the implementation is exactly the same.
    
    The new logic is being used for sanitizer builds which automatically
    target arm64 via the simulator, or if manually compiling an arm64
    simulator build on x64. I manually tested the latter.
    
    Also, the existing unit test is enabled for Mac (which was missing)
    and Windows now.
