Safe margin cleanup

Browse Source 
Safe margin property on CharacterBody only, used as argument in
move_and_collide.

Removed kinematic_safe_margin in 3D physics server, not really useful
and now harmonized with 2D.

Extra margin used for collision recovery when calling [method move_and_slide].
If the body is at least this close to another body, it will consider them to be colliding and will be pushed away before performing the actual motion.
A higher value means it's more flexible for detecting collision, which helps with consistently detecting walls and floors.
A lower value forces the collision algorithm to use more exact detection, so it can be used in cases that specifically require precision, e.g at very low scale to avoid visible jittering, or for stability with a stack of character bodies.
