d/jak2: finish jetboard training mission (mostly) and scouts mission (#2090)

The things that aren't working right now:
- returning the board (maybe cutscene related?)
  - draft until i see if this can be sorted out
- seems to need streaming audio as well, the `scene-player` gets
properly initialized from what i can tell
- had to hack around the streaming audio parts.
