Merge bitcoin/bitcoin#22677: cut the validation <-> txmempool circular dependency 2/2

Browse Source 
a64078e385 Break validation <-> txmempool circular dependency (glozow)
64e4963c63 [mempool] always assert coin spent (glozow)
bb9078ed51 [refactor] put finality and maturity checking into a lambda (glozow)
bedf246f1e [mempool] only update lockpoints for non-removed entries (glozow)
1b3a11e126 MOVEONLY: TestLockPointValidity to txmempool (glozow)

Pull request description:

  Remove 2 circular dependencies: validation - txmempool and validation - policy/rbf - txmempool

  Validation should depend on txmempool (e.g. `CChainstateManager` has a mempool and we often need to know what's in our mempool to validate transactions), but txmempool is a data structure that shouldn't really need to know about chain state.

  - Changes `removeForReorg()` to be parameterized by a callable that returns true/false (i.e. whether the transaction should be removed due to being now immature or nonfinal) instead of a `CChainState`. The mempool really shouldn't need to know about coinbase maturity or lockpoints, it just needs to know which entries to remove.
