Get the project compiling on Apple Silicon macOS natively (arm64) (#2827)

I havn't tested it yet, but I can almost guarantee that atleast `goalc`
will not work in the slightest!

But the project is atleast fully compiling. My hope is to start
translating some AVX to NEON next / get `goalc` working...eventually.
