Merge bitcoin/bitcoin#30344: kernel: remove mempool_persist

f1478c05458562a9bef5c2ba43959d758e7b4745 mempool: move LoadMempool/DumpMempool to node (Cory Fields)
6d242ff1e9ca02fd8f5cb3ffe82dfb48a52366cc kernel: remove mempool_persist.cpp (Cory Fields)

Pull request description:

  DumpMempool/LoadMempool are not necessary for the kernel.

  Noticed while working on instantiated logging.

  I suppose these could have been left in on purpose, but I'm assuming it was probably just an oversight.
