Pull request description:

  Continues the work of moving net_processing logic into PeerLogicValidation. See https://github.com/bitcoin/bitcoin/pull/19704 and https://github.com/bitcoin/bitcoin/pull/19607#discussion_r462032894 for motivation.

  This PR also renames `PeerLogicValidation` to `PeerManager` as suggested in https://github.com/bitcoin/bitcoin/pull/10756#pullrequestreview-53892618.

ACKs for top commit:
  MarcoFalke:
    re-ACK bb6a32ce99 only change is rebase due to conflict in struct NodeContext and variable rename 🤸
  hebasto:
    re-ACK bb6a32ce9983c72afa90f41a43a47ffd703ca006, only rebased, and added renaming `s/peer_logic/peerman/` into scripted-diff since my [previous](https://github.com/bitcoin/bitcoin/pull/19791#pullrequestreview-483118079) review (verified with `git range-diff`).
