Move logical onground/onroof updates to start of gamelogic

This reintroduces 2-frame edge-flipping after the 1-frame input delay
got removed. This is because along with processing input and moving
Viridian, logical onground/onroof assignments need to processed in the
same between-render sequence as well - otherwise Viridian only gets 1
frame of edge-flipping due to frame ordering.
