Add tests for `aria-owns` and hiding techniques in assorted scenarios
Companion tests for ARIA PR #1839: Clarify relationship between aria-hidden and aria-owns.
In development of that PR, I created a Codepen to manually test a few different scenarios involving combinations of aria-owns, aria-hidden, and host language hiding techniques.
This PR is my attempt to translate those scenarios into roughly comparable WPT tests. In the Codepen, I rendered a bunch of generic elements and manually tested their exposure in the accessibility tree as static text nodes.
In porting those scenarios into to this PR, I decided to leverage WPT’s get_computed_label() function and considered two markup testing approaches: name from author and name from content.
I chose name from content and tweaked each of my markup scenarios to use a parent button element, then compared my expected label to whatever accname was assembled for the button from its contents (involving a bunch of inner aria-owns, aria-hidden, and display: none; nonsense).
@adampage, I think you can mark this a "ready for review" because I'm guessing no one has taken a look yet since it is still draft :)
