f81fad5e0f3be1f7aed59f9da00396c75c2a6406 test: introduce and use `calculate_input_weight` helper (Sebastian Falbesoner)

Pull request description:

  Rather than manually estimating an input's weight by adding up all the involved components (fixed-size skeleton, compact-serialized lengths, and the actual scriptSig / witness stack items) we can simply take use of the serialization classes `CTxIn` / `CTxInWitness` instead, to achieve the same with significantly less code.

  The new helper is used in the functional tests rpc_psbt.py and wallet_send.py, where the previous manual estimation code was
  duplicated. Unit tests are added in the second commit.
