There are several cleanups here that are not just style nits... 1. The `common.isMainThread` was just a passthrough to the `isMainThread` export on the worker_thread module. It's use was inconsistent and just obfuscated the fact that the test file depend on the `worker_threads` built-in. By eliminating it we simplify the test harness a bit and make it clearer which tests depend on the worker_threads check. 2. The `common.isDumbTerminal` is fairly unnecesary since that just wraps a public API check. 3. Several of the `common.skipIf....` checks were inconsistently used and really don't need to be separate utility functions. A key part of the motivation here is to work towards making more of the tests more self-contained and less reliant on the common test harness where possible.
