A few extra determinism patches for Vehicle Framework (#413)

First one is for vehicle tweener - it's the same patch that MP applies to normal pawns, where during ticking it'll return the `TweenedPosRoot` instead of the actual tweened position. This will cause some minor graphical issues where projectiles will spawn outside of the vehicle turret, but will prevent situations where the projectile was spawned at a different position for each player.

The second one is changing the vehicle's rotation (Rot4) and angle (float) - both used to calculate vehicle's true rotation (Rot8). The change here is to not allow those 2 values to be modified while drawing (changes kept temporarily for drawing proper position, but then discarded).
