There are some complications here to handle unpackaged and packaged builds. In addition, there could be a difference between App prefs and GRE prefs. Since the underlying backgroundtasks code is built as part of Gecko (i.e., `toolkit/...` rather than `browser/...`) I have favoured GRE prefs. I think, however, that what is written will work for App-specific prefs, but I'm not concerned with that detail at this time. This also add tests for backgroundtask-specific prefs, which are structured as both xpcshell and mochitest-chrome tests because locally, the former tests unpackaged builds and the latter can accommodate testing packaged builds. We could use mochitest-chrome for both, but this has been pleasant to work with locally. Differential Revision: https://phabricator.services.mozilla.com/D97510
