[css-overflow] Add overscroll-behavior-[block/inline] in accordance with [css-logical]

[jonjohnjohnson]

In relation to both:

• #2179 Move overscroll-behavior spec from WICG to csswg-drafts
• #2000 Add overflow-block and overflow-inline to support CSS Writing Modes

Currently implementors are working with overscroll-behavior-y, overscroll-behavior-x, and shorthand overscroll-behavior. It seems like there will need to be a logical/relative set of these properties as well? With the same shorthand property inferring it's two value syntax?

Specs:

• https://wicg.github.io/overscroll-behavior/
• https://drafts.csswg.org/css-logical/

Seems reasonable!

BTW, I believe there was a resolution to introduce logical directions to overflow. Having overscroll-behavior match that is a good idea.

Since the specification has not moved yet, it would make more sense to create an issue against the spec in WICG. I will do so.
