Merge #19826: Pass mempool reference to chainstate constructor

Browse Source 
fa0572d0f3 Pass mempool reference to chainstate constructor (MarcoFalke)

Pull request description:

  Next step toward #19556

  Instead of relying on the mempool global, each chainstate is given a reference to a mempool to keep up to date with the tip (block connections, disconnections, reorgs, ...)
