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.
