Accept anchor-* as aliases of anchors-* in position-visibility

Reviewed by Antti Koivisto.
In https://github.com/w3c/csswg-drafts/issues/10201 the `anchors-visible`
keyword was renamed to `anchor-visible` to better reflect its behavior.
Renaming `anchors-valid` to match wasn't considered, so this question
was returned to the WG for consideration.
While they figure out what to do, we should accept both spellings,
to minimize the chances of compat problems down the line.

Add anchor-* variants of a couple tests to make sure it parses and behaves
correctly.
