Merge bitcoin/bitcoin#26499: wallet: Abandon descendants of orphaned coinbases

b0fa5989e1 test: Check that orphaned coinbase unconf spend is still abandoned (Andrew Chow)
9addbd7890 wallet: Automatically abandon orphaned coinbases and their children (Andrew Chow)

Pull request description:

  When a block is reorged out of the main chain, any descendants of the coinbase will no longer be valid. Currently they are only marked as inactive, which means that our balance calculations will still include them. In order to be excluded from the balance calculation, they need to either be abandoned or conflicted. This PR goes with the abandoned method.

  Note that even when they are included in balance calculations, coin selection will not select outputs belonging to these transactions because they are not in the mempool.

  Fixes #14148
