support c++ tools on macos (#2063)

Running reference tests/decompiler should now be possible on macos
(arm). Most of the changes were just cleaning up places where we were
sloppy with ifdefs, but there were two interesting ones:
- `Printer.cpp` was updated to not use a recursive function for printing
lists, to avoid stack overflow
- I replaced xxhash with another version of the same library that
supports arm (the one that comes in zstd). The interface is C instead of
C++ but it's not bad to use. I confirmed that the extractor succeeds on
jak 1 iso so it looks like this gives us the same results as the old
library.
