SG & FCPS visualization merge - Dec 22 2021

• Added FCPS visualization support for 3420.
• Merged saveglitch collision visualization onto FCPS. This allows you to have both visualizations active at the same time which can be very useful when trying to figure out exactly what out of bounds geometry FCPS events are going through.
  
  Note that spt-2013 for steampipe does not have FCPS visualization support, but does have saveglitch collision visualization support (it is from the sg-collision-vis branch).
  There may be a bug where text shown during FCPS animation flickers especially with high framerates, but hopefully this is not the case.

All FCPS related commands start with fcps_, all SG related commands start with y_spt_draw_portal_env.
