Write the deelevation-status enum value into the parent process, where it will (hopefully) show up in the event of a crash report. (Presenting this value more conveniently -- _e.g._, in `about:support` and/or Firefox telemetry -- would require additional plumbing, and so has been left to future work as bug 1774703.) This commit was previously submitted as D149546, and has not changed. Differential Revision: https://phabricator.services.mozilla.com/D152326
