Merge bitcoin/bitcoin#28154: test: refactor: deduplicate segwitv0 ECDSA signing for tx inputs 
83d7cfd542 test: refactor: deduplicate segwitv0 ECDSA signing for tx inputs (Sebastian Falbesoner)

Pull request description:

  This PR is a simple follow-up for #28025. It introduces a `signing_input_segwitv0` helper in order to deduplicate the following steps needed to create a segwitv0 ECDSA signature:
  1. calculate the `SegwitV0SignatureHash` with the desired sighash type
  2. create the actual digital signature by calling ECKey.sign_ecdsa on the signature message hash calculated above
  3. put the DER-encoded result (plus sighash byte) at the bottom of the witness stack
