Also added signed long and unsigned long behind a NEED_LONG_INT define like the main repo. Frankly, I don't know how imperative this was, as the define is only used in iOS builds which I don't even think GDExtension supports, but the other int types were being ported over anyway so might as well

Thanks! This makes sense to me

GDExtension does support iOS builds, however, we don't ever define NEED_LONG_INT in the godot-cpp build system. Looking at Godot's build system it's defining it on iOS with arm64, so we should probably update the build system here to do the same.

This will need a rebase after PR #1299 in order for tests to pass

Rebased the repo & updated the iOS build system to use NEED_LONG_INT! I've never built for iOS so I wouldn't know how to test the change, but I included the define where it would reasonably be expecting an arm64 architecture. Because of the added "universal" option, the check was tweaked to ensure it's explicitly not x86_64

Thanks! This looks good to me, but I'm also not very experienced with iOS.

@bruvzg Do the iOS bits make sense to you?

Cherry-picking to 4.1 in #1373
