[jak3] Fix flashing with maker projectiles (#3702)

Browse Source 
Fix https://github.com/open-goal/jak-project/issues/3701, and possibly
other issues where projectiles were invisible/messed up. The use of
`align16` with the -16 was subtracting 16 in cases when the pointer was
already aligned, causing a bad value to be loaded for the quaternion.

I also renamed some variables and did some manual cleanup on a method in
process-drawable, since this one comes up a lot during debugging.
