psbt: if a transaction has witnesses/scriptSig set, add it to psbt
...
For any transaction that's got 'finalized' signature data for an input,
we should add this information to the psbt also

psbt: add method to confirm 'finalized' status of psbt
...
calling `wally_psbt_finalize` doesn't return a status indicator; instead
you must call `psbt_is_finalized` to check that it's eligible for
'extraction' -- extraction will fail if the psbt is not in a finalized
state.

psbt: create new_psbt method
...
Move all psbt creation into single method, new_psbt
note that if a psbt is init'd for a transaction that's
deserialized with scripts etc already attached, then set_global_tx
will fail. instead, we empty all of this out first.
if the tx is being re-init'd from a tx source that had a psbt attached
(e.g. fromwire_) then the script/witness data will get populated
appropriatel from there.
