feat(aria/lookupTable, aria-allowed-attr): deprecate aria.lookupTable and passing allowed attributes to aria-allowed-attr

[straker]

This pr officially closes #2108 as it removes all lookup table references in our codebase expect where we still need it (mostly for implicitNodes which is deprecated as well and keeping lookupTable as a public API).

I noticed the aria-allowed-attr test still used the lookup table to configure the options test, which shouldn't have worked. Digging further I found multiple things wrong with that test that would cause it to never fail.

First, without mccheddarton being configured into the standards object, the check would always pass as there was no allowed role data for an invalid role. Second, since aria-snuggles was not configured into the standards object, it would not be counted as a valid attribute so wouldn't fail on it either. Lastly, even if those were configured, since we pass the options to force the allowed attrs the test could never fail.

So to fix it I added an assert that proved that without the options the check should fail, which requires properly configured standards.

I also deprecated the options to ara-allowed-attrs as we had done with aria-required-attrs, and refactored the code while I was there to not use var.

Closes issue: #2108
