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.

Previously when checking the initial timing we did a lot of checks
after accessing and copying timing.duration and before we check
that timing.duration is roughly the same as performance.now(),
which can lead to flakes if the overhead of the checking is
big enough. Update the test to check timing.duration against
performance.now() as soon as possible when it's copied instead
of computed.

Previously the test makes several assumptions about the absolute
values of the nodeTiming fields, which can make the test flaky
on slow machines. This patch rewrites the test to check the
relative values instead. It also updates the test to make it
work with workers instead of directly skipping in workers.

* Update the user timing implementation to conform to
User Timing Level 3.
* Reimplement user timing and timerify with pure JavaScript
implementations
* Simplify the C++ implementation for gc and http2 perf
* Runtime deprecate additional perf entry properties
in favor of the standard detail argument
* Disable the `buffered` option on PerformanceObserver,
all entries are queued and dispatched on setImmediate.
Only entries with active observers are buffered.
* This does remove the user timing and timerify
trace events. Because the trace_events are still
considered experimental, those can be removed without
a deprecation cycle. They are removed to improve
performance and reduce complexity.

This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.
The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.
This has the side effect that `common` is used significantly less
frequent.
