Doc clarity/detail for extra spacing properties

Re: Space spacing being in addition to character spacing see:

 * <d7b85fbaa1/scene/resources/dynamic_font.cpp (L858-L859)>

Re: Value being able to be negative see example here:

 * <https://github.com/godotengine/godot/issues/38630>

But also note that nodes other than `Label` may not currently render extra space spacing correctly.
