Got OpenGOAL building and running natively on Apple Silicon.
This is the rest of the port after the smaller arm64 emitter PRs. I was
told pushing one big PR was okay. This covers goalc, the runtime,
linker, kernel and the GOAL asm.
The new paths have native tests. I also found four more emitter bugs
while running it. They're in scalar sqrt, 128-bit stores, scalar max and
indexed stores above 4 GB.
Spent a while cleaning it up so it's easier to read. 4am gotta sleep lol
Closes#3841
