Add API to worker thread to check whether main thread is TTY

What is the problem this feature will solve?

In worker threads, process.stdout.isTTY and process.stderr.isTTY are undefined. However, they do forward stdout/stderr to the main thread, and the main thread could potentially be isTTY === true. This makes sense as some things don't work, like raw mode. However, things that produce colors would want to be able to detect that the main thread is TTY, so colors can be shown when logged from a worker thread.

What is the feature you are proposing to solve the problem?

Add an API to worker threads to check whether stdout/stderr in the main thread is TTY.

This is needed for color packages like chalk to be able to support showing colors when running in worker threads.

Beginne mit dem Lesen der worker_threads API und des zugehörigen Issues #26946 und verfolge anschließend, wie sich process.stdout.isTTY und process.stderr.isTTY verhalten, wenn die Ausgabe von einem Worker weitergeleitet wird. Die Aufgabe ist erfüllt, wenn die vorgeschlagene Worker-Thread-API den TTY-Zustand von stdout und stderr des Haupt-Threads erkennen kann und den Anwendungsfall des color-package abdeckt.
