Merge bitcoin/bitcoin#22415: Make m_mempool optional in CChainState

Browse Source 
ceb7b35a39 refactor: move UpdateTip into CChainState (James O'Beirne)
4abf0779d6 refactor: no mempool arg to GetCoinsCacheSizeState (James O'Beirne)

617661703a validation: make CChainState::m_mempool optional (James O'Beirne)

Pull request description:

  Make `CChainState::m_mempool` optional by making it a pointer instead of a reference. This will allow a simplification to assumeutxo semantics (see https://github.com/bitcoin/bitcoin/pull/15606#pullrequestreview-692965905) and help facilitate the `-nomempool` option.
