James M Snell 8caa1dcee6 test: rely less on duplicative common test harness utilities
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.
