Overhaul spectator icon handling and rendering

- Optimize and improve 3D icon drawing
- Combine 2D and 3D PFHs into 1
- Render group icons outside of 200m, unit icons within
- Store list of groups on units update to cut down on what needs to be done each frame
- Change map control type to 100 to remove all default unit icons
- Improve colour caching, group colours don't change, unit colours do
- Remove icon setting, toggling should be at users discretion
