Note that this patch only transforms the use of the nsDataHashtable type alias to a directly equivalent use of nsTHashMap. It does not change the specification of the hash key type to make use of the key class deduction that nsTHashMap allows for in some cases. That can be done in a separate step, but requires more attention. Differential Revision: https://phabricator.services.mozilla.com/D106008
