Pull request description:

  ## Issue being fixed or feature implemented
  It reduces circular dependencies and simplify code.

  ## What was done?
  Removed circular dependency over PeerManager for llmq::QuorumBlockProcessor, llmq::CEhfSignals, llmq::ChainLocks, and several extra useful refactorings: see commits.

  ## How Has This Been Tested?
  Run `test/lint/lint-circular-dependencies.sh`

  ## Breaking Changes
  N/A
