Implement `MessagePort` and `MessageChannel` along the lines of
the DOM classes of the same names. `MessagePort`s initially
support transferring only `ArrayBuffer`s.
Thanks to Stephen Belanger for reviewing this change in its
original form, to Benjamin Gruenbaum for reviewing the
added tests in their original form, and to Olivia Hugger
for reviewing the documentation in its original form.

This commit is to help in the effort to name all anonymous
functions to help when heap debugging. The issue asked for
any functions to be updated that are not on a prototype
and this file contains one function that meets those needs.
A previous pull request (13849) was not completed and did
not meet the requirements of the issue so this PR looks
to complete that.

Provide named exports for all builtin libraries so that the libraries
may be imported in a nicer way for esm users. The default export is left
as the entire namespace (module.exports) and wrapped in a proxy such
that APMs and other behavior are still left intact.

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.

This makes a effort to make sure all of these errors will actually
also show the received input.
On top of that it refactors a few tests for better maintainability.
It will also change the returned type to always be a simple typeof
instead of special handling null.

This adds a rule that forbids the use of native Error constructors in
the `lib` directory. This is to encourage use of the `internal/errors`
mechanism. The rule is disabled for errors that are not created with
the `internal/errors` module but are still assigned an error code.
