Merge #15971: validation: Add compile-time checking for negative locking requirement in LimitValidationInterfaceQueue

62d50ef308 Add LOCKS_EXCLUDED(cs_main) to LimitValidationInterfaceQueue(...) which does AssertLockNotHeld(cs_main) (practicalswift)

Pull request description:

  This PR adds compile-time checking for negative locking requirements that follow from the run-time locking requirement `AssertLockNotHeld(cs_main)` in `LimitValidationInterfaceQueue(...)`.

  Changes:
  * Add `LOCKS_EXCLUDED(cs_main)` to `LimitValidationInterfaceQueue(...)` which does `AssertLockNotHeld(cs_main)`
  * Add `LOCKS_EXCLUDED(cs_main)` to `CChainState::ActivateBestChain(…)`, `CChainState:: InvalidateBlock(…)` and `CChainState::RewindBlockIndex(…)` which all call `LimitValidationInterfaceQueue(...)` which does `AssertLockNotHeld(cs_main)`
  * Add `LOCKS_EXCLUDED(cs_main)` to `InvalidateBlock(…)` which calls `CChainState::InvalidateBlock(...)` which in turn calls `LimitValidationInterfaceQueue(...)` which  does `AssertLockNotHeld(cs_main)`
  * Add `LOCKS_EXCLUDED(cs_main)` to `RewindBlockIndex(…)` which calls `CChainState::RewindBlockIndex(...)` which in turn calls `LimitValidationInterfaceQueue(...)` which does `AssertLockNotHeld(cs_main)`
