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.
