[Physics] Update WorldMatrix when forcing transformation on PhysicsComponent

[Eideren]

PR Details

UpdatePhysicsTransformation() is likely to set the transformations of the physics-engine side object based on previous frame transformation instead of latest, see summary of WorldMatrix to explain why. It makes sense that an Update function works with up to date data, so this looks more like a bug to me.

More context here https://github.com/stride3d/stride/pull/1401#discussion_r850608711 and in the discussion further below.

Also took the time to clean things up a bit.
