Bug 1790317 part 2: Change instances of UniqueID in LocalAccessible code to use ID. r=eeejay This doesn't update usage elsewhere in the code base, but it should be enough to ensure that this doesn't break anything. We can gradually update other cases in future. Differential Revision: https://phabricator.services.mozilla.com/D157082
