feat: Pseudo peer and staged sync

For simplicity, we use with_pow() + pseudo peer that connects to reth itself, so that it can support 1. StateFetcher via NetworkState 2. Block announcement (which requires with_pow()).

For block announcement, another way was using ImportService like before, or calling engine_api. But for simplicitiy, for now we just publish from pseudo peer like pre-PoS, hence with_pow().
