Merge bitcoin/bitcoin#25951: log: Move validation option logging to LoadChainstate()

fa4c59d65bdf1c64056b18a58f8aaa2800995aa6 Move blockstorage option logging to LoadChainstate() (MacroFake)
fa3358b668d8415adc1b5586caa382fe4140ad42 Move validation option logging to LoadChainstate() (MacroFake)

Pull request description:

  This would allow libbitcoinkernel users to see the options logged as well. Currently they would only be logged for bitcoind. Behavior change suggested in the refactoring pull https://github.com/bitcoin/bitcoin/pull/25704#discussion_r956166460

ACKs for top commit:
  ryanofsky:
    Code review ACK fa4c59d65bdf1c64056b18a58f8aaa2800995aa6. Only change since last review is moving pruning logprints out of `AppInitParameterInteraction` as suggested
