fix(extra-natives/rdr3): graphic natives flickering

[Ehbw]

Goal of this PR

Resolves flickering within several graphic natives (DRAW_BOX/DRAW_POLY/DRAW_LINE) caused by a race condition. This should also resolve several crashes tied to these natives but these crashes were unable to be reproduced. SET_DRAW_ORIGIN has been changed to fix #2450 and the flickering regression reported in #3082
