feat(server): native fetch implementation support for Node

[ardatan]

Changes & Notes;

• Add a benchmark scenario that uses @whatwg-node/server with the native fetch
  • It is faster than older Node version but still slower than @whatwg-node/node-fetch ponyfill
  • See feat(server): native fetch implementation support for Node #1328 (comment)
• Add a test scenario for unit tests of @whatwg-node/server with the native fetch
  • It is fully compatible in terms of functionality but when you create a proxying server with native fetch, it is flakey and sometimes leaks according to Jest on Node 18 and Node 22. See proxy.spec.ts
  • Every single unit test is now done both the ponyfill and the native fetch
• Introduce a new flag in createFetch of @whatwg-node/fetch to use the native Fetch implementation, so native Fetch impl can be used with @whatwg-node/server
