This adds a test to ensure that crash reporting works inside of `application --backgroundtask ...` invocations. A test-only `crash` task is added that uses `CrashTestUtils.jsm` to trigger a crash. The `xpcshell` harness invokes that background task and processes any minidump and extras just as it does for existing `xpcshell` subprocesses. The test is homed in `toolkit/crashreporter`, rather than in `toolkit/components/backgroundtasks`, because there is special handling for `CrashTestUtils.jsm` and the `testcrasher` library. It's probably possible to make that infrastructure usable from multiple locations but it seems low value. Differential Revision: https://phabricator.services.mozilla.com/D98096
