This turns on discovery v5 by default. It adds `--discovery.v4` so you can also disable v4. It prefers to use disc v5 for node resolution. Most other changes are minimal changes from geth to maintain clean diff and updated behaviour around sources. I expect there will be some rough edges but the sooner v5 is active in main the sooner those will come up. Running with `--discovery.v4=false` might be worthwhile for testing, and maybe in some QA workflows.

Enables discv5 for 3.3 for #18195. Duplicates #18578 from main.
I think we want discv5 enabled in 3.3 if we want to meet the Jan 31 target. I wonder if we want to keep the resolution leaning toward discv4 for 3.3.
