decomp: finish _almost all of_ the remaining camera code

[xTVaser]

• cam-master
  • main event handler casts all return values to none
• pov-camera
• cam-states
  • finished, need to adjust the res-lump macros
• cam-states-dbg
• cam-debug
  • camera-line-dma / camera-line2d not done -- confusing as to what is passed in that is accessed at offset 1792
• cam-layout
  • a single function - cam-layout-save-cam-trans make an issue!

reviewed up to cam-state-dbg.gc

interesting. It really seems like children of process-drawable can customize root to be whatever they want. I wonder if there was a built in language feature for this that we are missing in OpenGOAL. None of these show up in inspect method, so it seems like they aren't normal overlays (which do show up in inspects)

[water111]

wow this part is awful

[water111]

reviewed up to cam-start.gc (again)

there's some messed up bitfield stuff in this function, but probably okay to leave for now
