Adds Node-side coverage for the WHATWG Headers API and a fetch/headers benchmark.

These tests are not from WPT. They cover constructor init, get/set/append/delete, set-cookie / getSetCookie(), iteration (including mutation during iteration), validation, brand checks, and util.inspect.

The implementation change lives in undici:

Adds Node-side coverage for the WHATWG Headers API and a fetch/headers benchmark.

These tests are not from WPT. They cover constructor init, get/set/append/delete, set-cookie / getSetCookie(), iteration (including mutation during iteration), validation, brand checks, and util.inspect.

The implementation change lives in undici:

Adds Node-side coverage for the WHATWG Headers API and a fetch/headers benchmark.

These tests are not from WPT. They cover constructor init, get/set/append/delete, set-cookie / getSetCookie(), iteration (including mutation during iteration), validation, brand checks, and util.inspect.

The implementation change lives in undici:
