Merge bitcoin/bitcoin#23465: Remove CTxMemPool params from ATMP

Browse Source 
f1f10c0514 Remove CTxMemPool params from ATMP (lsilva01)

Pull request description:

  Remove `CTxMemPool` parameter from `AcceptToMemoryPool` function, as suggested in https://github.com/bitcoin/bitcoin/pull/23437#issuecomment-962536149 .

  This requires that `CChainState` has access to `MockedTxPool` in  `tx_pool.cpp` as mentioned https://github.com/bitcoin/bitcoin/pull/23173#discussion_r731895386. So the `MockedTxPool` is attributed to `CChainState::m_mempool` before calling `AcceptToMemoryPool`.

  Requires #23437.
