Pull request description:

  Includes some commits to address follow-ups from #27021: https://github.com/bitcoin/bitcoin/pull/27021#issuecomment-1554675156

  Reduces the effective value of unconfirmed UTXOs by the fees necessary to bump their ancestor transactions to the same feerate.

  While the individual UTXOs always account for their full ancestry before coin-selection, we can correct potential overestimates with a second pass where we establish the ancestry and bump fee for the whole input set collectively.

  Fixes #9645
  Fixes #9864
  Fixes #15553
