LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere!

LibWeb: Add "parallel queue" and allow it as fetch task destination Note that it's not actually executing tasks in parallel, it's still throwing them on the HTML event loop task queue, each with its own unique task source. This makes our fetch implementation a lot more robust when HTTP caching is enabled, and you can now click links on https://terminal.shop/ without hitting TODO assertions in fetch. 2025-07-16 12:29:26 +02:00			`IncrementalReadLoopReadRequest(GC::Ref<Body>, GC::Ref<Streams::ReadableStreamDefaultReader>, TaskDestination, Body::ProcessBodyChunkCallback, Body::ProcessEndOfBodyCallback, Body::ProcessBodyErrorCallback);`
