feat: draw cinematic camera path

[ThisAMJ]

• Draws camera path
• Shows keyframe points in red, and current cinematic position in yellow, as lil' camera boxes
  • Of course, FOV, roll, and aspect ratio etc is taken into account when drawing them
• Controlled by sar_cam_path_draw, disabled by sar_cam_control 2
• Added sar_cam_path_goto to tp to a certain frame in drive mode
• Removed sar_cam_path_showkfs in favor of sar_cam_path_getkfs

See P2SR Discord for discussion, I settled on this shape for the lil' camera boxes
