[jak3] A bunch of small fixes to get game.cgo to load (#3435)

The `test-play` macro is back, though it doesn't call `play` yet. We can
at least load all of `game.cgo`, which involves loading a lot of the
code we've decompiled, loading/linking objects files compiled by
OpenGOAL (like dir-tpages), and loading/linking Jak's art-groups (for
jak 3 they are stored v5 format that I added to the linker).

There were no major issues - just a few forgotten mips2c entries and
minor bugs/functions that needed stubs. Most of the work was updating
the linker. Hopefully I'll never have to touch that code again - I think
it supports everything we need for jak 3!
