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.
