Migrates all code, there should be no change in the compilation output (linter should check this) At first i was considering making these builtins, which short of a bunch of code generation, would require some sort of dynamic definition in `Atoms.cpp`. This isn't hard but, i figured it would be better to keep it simple and just generate the OG macros. Fixes https://github.com/open-goal/jak-project/issues/233
