Add normative text on calculating aria-level, aria-posinset, and aria-setsize
Closes #1194
As discussed in the issue, this PR adds normative wording on requiring user agents to calculate aria-level, aria-posinset, and aria-setsize. It also adds a section outlining how to compute each attribute, based on the current Core AAM wording that will be removed after this is merged.

@smhigley unfortunately, this disconnects the old comments from the lines in the rebased commit. I hope the thread is sufficient to reconstruct.
@smhigley I think you never got to @pkra review on this is one?
and @pkra, you added agenda but then we didn't end up discussing this. Do we still need to discuss?

Not from my end.
@rahimabdi wanted your review here to make sure this doesn't add any snags for IDL mappings (based on what was said in the call I think this may not affect IDL, but would be nice to get your review to confirm)
