Merge bitcoin/bitcoin#23997: wallet: avoid rescans under assumed-valid blocks 
817326a828 wallet: avoid rescans if under the snapshot (James O'Beirne)

Pull request description:

  This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11) (parent PR: #15606)

  ---

  Refuse to load a wallet if it requires a rescan lower than the height of assumed-valid blocks.

  Of course in live code right now, `BLOCK_ASSUMED_VALID` block index entries don't exist since they're a unique flag introduced by the use of UTXO snapshots, so this is prophylactic code exercised only by unittests.

ACKs for top commit:
  achow101:
    ACK 817326a828
  ryanofsky:
    Code review ACK 817326a828. This seems like the simplest change we can make to avoid wallet problems when an assumeutxo snapshot is loaded.

src/node/

The src/node/ directory contains code that needs to access node state (state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar classes).

Code in src/node/ is meant to be segregated from code in src/wallet/ and src/qt/, to ensure wallet and GUI code changes don't interfere with node operation, to allow wallet and GUI code to run in separate processes, and to perhaps eventually allow wallet and GUI code to be maintained in separate source repositories.

As a rule of thumb, code in one of the src/node/, src/wallet/, or src/qt/ directories should avoid calling code in the other directories directly, and only invoke it indirectly through the more limited src/interfaces/ classes.

This directory is at the moment sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
