validation: use stronger EXCLUSIVE_LOCKS_REQUIRED()
https://github.com/bitcoin/bitcoin/pull/24103 added annotations to
denote that the callers of `CChainState::ActivateBestChain()` and
`CChainState::InvalidateBlock()` must not own `m_chainstate_mutex` at
the time of the call.
Replace the added `LOCKS_EXCLUDED()` with a stronger
`EXCLUSIVE_LOCKS_REQUIRED()`, see
https://clang.llvm.org/docs/ThreadSafetyAnalysis.html#negative for the
difference between both.
