This patch is developed from D104136#3396152. This patch creates WorkerTestUtils.webidl under dom/webidl for testing workers with internal APIs. These APIs are exposed to workers only and controlled by dom.workers.testing.enabled pref. This patch creates a Mozilla-specific web-platform test, testing/web-platform/mozilla/test/workers/worker_timer_nesting_level.html, to test the timer nesting level implementation for workers. To simplify the test implementation, this patch does not implement the webidl under dom/chrome-webidl/ suggested by D104136#3396152. Depends on D104136 Differential Revision: https://phabricator.services.mozilla.com/D105332
