It caused us substantial confusion investigating this bug under the belief that StartRemoteDrawingInRegion may have been modifying the dirty region. None of our existing widget code anymore uses the API in this way, so it makes sense to just force this dirty region to be const so that we no longer support the assumption and alleviate confusion in the future about how our widget code actually behaves. Depends on D106246 Differential Revision: https://phabricator.services.mozilla.com/D106247
