refactor: use resourceForReadableStream for fetch (#20217)
Switch `ext/fetch` over to `resourceForReadableStream` to simplify and unify implementation with `ext/serve`. This allows us to work in Rust with resources only. Two additional changes made to `resourceForReadableStream` were required: - Add an optional length to `resourceForReadableStream` which translates to `size_hint` - Fix a bug where writing to a closed stream that was full would panic
