These APIs allow arbitrary, cloneable JavaScript values to be set and
passed to all new Worker instances spawned from the current context.
It is similar to `workerData` except that environment data is set
independently of the `new Worker()` constructor, and the the value is
passed automatically to all new Workers.
This is a *partial* fix of https://github.com/nodejs/node/issues/30992
but does not implement a complete fix.

When a Worker is terminated, its own handle and the public
`MessagePort` are `.ref()`’ed, so that all relevant events,
including the `'exit'` events, end up being received.
However, this is problematic if messages end up being queued
from the Worker between the beginning of the `.terminate()` call
and its completion, and there are no `'message'` event handlers
present at that time. In that situation, currently the messages
would not end up being processed, and since the MessagePort
is still `.ref()`’ed, it would keep the event loop alive
indefinitely.
To fix this:
- Make sure that all messages end up being received by
`drainMessagePort()`, including cases in which the port had
been stopped (i.e. there are no `'message'` listeners) and
cases in which we exceed the limit for messages being processed
in one batch.
- Unref the Worker’s internal ports manually after the Worker
has exited.
Either of these solutions should be solving this on its own,
but I think it makes sense to make sure that both of them
happen during cleanup.

Allow calling eventLoopUtilization() directly on a worker thread:
const worker = new Worker('./foo.js');
const elu = worker.performance.eventLoopUtilization();
setTimeout(() => {
worker.performance.eventLoopUtilization(elu);
}, 10);
Add a new performance object on the Worker instance that will hopefully
one day hold all the other performance metrics, such as nodeTiming.
Include benchmarks and tests.
