worker: process.argv for workers

Is your feature request related to a problem? Please describe.
process.argv is commonly used in Node.js. Right now there is only execArgv for altering how node instance works, which will be filtered process.argv with these only Node.js understands.

Describe the solution you'd like
Add an option argv to Worker constructor's second argument.

new Worker(__filename, { argv: ['foo', 'bar'] })
if (!isMainThread) {
  console.log(process.argv) // ['foo', 'bar']
}

Describe alternatives you've considered
Just use option workerData in Worker constructor's second argument.

@legendecas Feel free to open a PR with this if you like – I think you can pass it around the same way that we pass workerData.

I would suggest process.argv to follow the standard format though, i.e. process.argv[0] is the Node.js binary being used and process.argv[1] is the main script name (of the Worker thread, in this case).

@addaleax

@addaleax 😄 I'd like to. Just open the issue to ask around if it was left there intentionally.

@legendecas

@legendecas As far as I am concerned, workerData was intended to be the (far more powerful) alternative that we’d use for worker threads, but I don’t personally see any issue with adding a more main-thread-like process.argv.
