This revision is a step towards ensuring we get the right domains for known accessibility instantiators. We want to anticipate the needs of known clients and make sure we have all the cache domains ready, especially for heavy-use clients like screen readers. The domains we'll need are a bit of a work in progress, but can be updated easily. For now, err on the side of caution. This revision also implements better client detection on macOS, so we can handle multiple clients. Differential Revision: https://phabricator.services.mozilla.com/D220035
