Remove support for multiple arguments (which don't actually work for
EventTarget). Use our EventTarget implementation rather than a mock.
Refactor `once` code in preparation of `on` using shared code for
supporting `on` with `EventTarget`s.
Support EventTarget in the `events.on` static method

Fix removeListener when eventName type is 'symbol'.
```js
const EventEmitter = require('events');
const myEmitter = new EventEmitter();
const sym = Symbol('symbol');
const fn = () => { };
myEmitter.on(sym, fn);
myEmitter.on('removeListener', (...args) => {
console.log('removeListener');
console.log(args, args[0] === sym, args[1] === fn);
});
myEmitter.removeAllListeners()
```
When the listener's eventName type is 'symbol' and removeListener is
called with no parameters, removeListener should be emitted.

Installing an error listener has a side effect that emitted errors are
considered as handled. This is quite bad for monitoring/logging tools
which tend to be interested in errors but don't want to cause side
effects like swallow an exception.
There are some workarounds in the wild like monkey patching emit or
remit the error if monitoring tool detects that it is the only listener
but this is error prone and risky.
This PR allows to install a listener to monitor errors with the side
effect to consume the error. To avoid conflicts with other events it
exports a symbol on EventEmitter which owns this special meaning.

For unhandled `'error'` events, include the constructor name for
subclasses of EventEmitter, if possible. This makes tracing errors
easier when both creation of the `Error` object and emitting it
happen in code that does not refer back to the event emitter.

Previously the enhancement were done right after emitting
`'uncaughtException'`, which meant by the time we knew the
exception was fatal in C++, the error.stack had already been
patched.
This patch moves those routines to be called later during the
fatal exception handling, and split them into two stages:
before and after the inspector is notified by the invocation of
`V8Inspector::exceptionThrown`. We now expand the stack to include
additional informations about unhandled 'error' events before
the inspector is notified, but delay the highlighting of the
frames until after the inspector is notified, so that the
ANSI escape sequences won't show up in the inspector console.

This adds the constructor name of the event target to the emitted
warning. Right now it's difficult to identify where the leak is
actually coming from and having some further information about the
source will likely help to identify the source.

currently the first module loaded during bootstrap, it is
fine to load it eagerly. We just need to make sure

If there is no handler for `.emit('error', value)` and `value`
is not an `Error` object, we currently just call `.toString()`
on it.
Almost always, using `util.inspect()` provides better information
for diagnostic purposes, so prefer to use that instead.
