Collision state of `CharacterBody3D` is also updated when calling `CharacterBody3D#apply_floor_snap()`

[Togira123]

Your Godot version:
4.4.beta
Issue description:
As the title says, the return value of all is_on_*() methods might change when running apply_floor_snap(), but the documentation says it only changes when calling move_and_slide(). This is because the method that updates the state (_set_collision_direction()) is also called inside of apply_floor_snap(). Not sure if all values realistically can change, perhaps, only is_on_floor() can, but I'd include them regardless since _set_collision_detection() can definitely change them. The documentation of all the is_on_*() methods should be updated to include that extra information.

The same goes for CharacterBody2D.
