Merge bitcoin/bitcoin#25168: refactor: Avoid passing params where not needed

Browse Source 
fa1b76aeb0 Do not call global Params() when chainman is in scope (MacroFake)
fa30234be8 Do not pass CChainParams& to PeerManager::make (MacroFake)
fafe5c0ca2 Do not pass CChainParams& to BlockAssembler constructor (MacroFake)
faf012b438 Do not pass Consensus::Params& to Chainstate helpers (MacroFake)
fa4ee53dca Do not pass time getter to Chainstate helpers (MacroFake)

Pull request description:

  It seems confusing to pass chain params, consensus params, or a time function around when it is not needed.

  Fix this by:

  * Inlining the passed time getter function. I don't see a use case why this should be mockable.
  * Using `chainman.GetConsensus()` or `chainman.GetParams()`, where possible.
