Issue Description

Expectation

aria-expanded is an allowed attribute on both menuitemcheckbox and menuitemradio (ref: https://w3c.github.io/aria/#menuitemcheckbox).

Actual

axe-core currently returns an aria-allowed-attr failure when it is added to either role.

How to Reproduce

Simplest repro: https://jsfiddle.net/fu9ve7gp/show

Additional context

Looks like the issue is here: https://github.com/dequelabs/axe-core/blob/develop/lib/standards/aria-roles.js#L377-L396

#3343 would fix it along with some other aria-expanded support mismatches, but since it's over a year old I wasn't sure if it was still active.
