Add macOS ARM64 (Apple Silicon) support.

FWIW I'm using the dylib linked in the description on my M1 MacBook Pro and everything seems to be working correctly from what I've tested so far.

And it looks like the godot-cpp repo has a PR that's been merged to add ARM support on macOS now? (different from the PR linked in this one's description)

It is, but without godotengine/godot-cpp#587, there's no way to build both architectures without an extra hack (copying godot-cpp files around, to avoid it overwriting it). Also, it will need extra lipo call, since merged PR do not have support for universal builds.

Should this PR be merged now? We can run the lipo step manually on CI to create an universal library, as long as we know the exact command to use.

The scons option names added in https://github.com/godotengine/godot-cpp/pull/584/files seem to be different than the ones mentioned in this PR, but it doesn't seem hard to port these changes to suit the changes that were finally merged into godot-cpp because thanks to this PR we know where we need the architecture changes

Updated to the last godot-cpp changes, now it should work.
Fresh binary for testeing: libgitapi.dylib.zip

The current build failure in mac just seems to be related to using the build config argument that goes into build_libs_mac.sh. I guess it just needs to use $1 instead release or debug in the file path.

There is a catch here that $1 is documented to be Release or Debug instead of their lowercase counterparts

Thanks a lot! I didn't have an M1 system but since people have already tested the builds, this helps a ton!
