Merge #13527: policy: Remove promiscuousmempoolflags

faa24441ec047ec336b86f586016b9d318c1c0ad policy: Remove promiscuousmempoolflags (MarcoFalke)

Pull request description:

  It seems odd to clutter validation code with features that can only ever be used for testing (testnet or regtest). Removing that test-only code makes the mempool logic less painful to understand and easier to reason about when changed or refactored in the future.
