`common.hasTracing` is only used in one place. `common` is bloated so
let's move that to the one test that uses it.
`hasTracing` is undocumented so there's no need to remove it from the
README file as it's not there in the first place.
Similarly, it's not included in the .mjs version of the `common` file.

Enable running tests inside workers by passing `--worker`
to `tools/test.py`. A number of tests are marked as skipped,
or have been slightly altered to fit the different environment.

Removes the requirement to use `--trace-events-enabled` to enable
trace events. Tracing is enabled automatically if there are any
enabled categories.
Adds a new `trace_events` module with an API for enabling/disabling
trace events at runtime without a command line flag.
```js
const trace_events = require('trace_events');
const categories = [ 'node.perf', 'node.async_hooks' ];
const tracing = trace_events.createTracing({ categories });
tracing.enable();
// do stuff
tracing.disable();
```
Multiple `Tracing` objects may exist and be enabled at any point
in time. The enabled trace event categories is the union of all
enabled `Tracing` objects and the `--trace-event-categories`
flag.
