Merge #19597: test: test decodepsbt fee calculation (count input value only once per UTXO) 
82dee87933ed0714976ff4eb9657acfc13c6de84 test: test decodepsbt fee calculation (count input value only once per UTXO) (Sebastian Falbesoner)

Pull request description:

  Fixes #19523, adding a simple test to `rpc_psbt.py` that checks that the decodepsbt fee matches the one given by the wallet (`walletcreatefundedpsbt`). This is in particular important for PSBTs with segwit inputs that have both a witness- and a non-witness-UTXO type set.

  Example test run after reverting commit 75122780e2c46505d977e24c5612dfa9442ab754 ("Increment input value sum only once per UTXO in decodepsbt"):
