[selectors] Add new :focus-visible tests
These tests check what happens when an active element
matches (or not) :focus-visible, and a script causes focus
to move elsewhere.
Basically these are tests for the next two points of the spec
(https://drafts.csswg.org/selectors-4/#the-focus-visible-pseudo):
"
* If the active element matches :focus-visible, and a script
causes focus to move elsewhere, the newly focused element
should match :focus-visible.
* Conversely, if the active element does not match :focus-visible,
and a script causes focus to move elsewhere,
the newly focused element should not match :focus-visible.
