[jak2] add pal decomp support (#2434)

Unsure what hacks or type casts might eventually be needed for the PAL
version, but these changes are enough to get things to extract and run
the game (though the extract phase requires iso_data to be in a jak2_pal
folder, but the build still looks for jak2 in iso_data and
decompiler_out).
