[Bug] Part 1: Indicate that role=directory will be deprecated (aria 1.2)

[scottaohara]

ARIA 1.2 is deprecating the directory role, as in reality it had no practical difference between a role=list.

ARIA in HTML is being updated to call out that authors should not use this role, and request that conformance checkers warn authors to instead use a HTML list element, or role=list instead.

role=directory test case

Need to discuss with team what level deprecated features should be reported at. My gut feels like it should be a recommendation.

[scottaohara]

Makes sense. FYI, I updated the test case to mention additional issues i've found with role=directory's implementation. Essentially, not only does using role=directory on a ul, ol, or menu do nothing to change its exposed mapping, it actually breaks the mapping of the nested li elements in Chromium specifically. So if used, authors need to also specify role=listitem on all li elements to mitigate this behavior.

Note: Create a rule where the role is tokenized (Maybe look for a deprecated attribute in the ARIA spec file)

Agreement in triage into make this into a Recommendation

close this and reopen for the next sprint per team process: #680

some deprecated aria attributes/roles were added to the engine, but no test cases were written.
