refactor: use PSBTFillOptions for filling and signing

Replace the sign, finalize , bip32derivs and sighash_type arguments which
are passed to FillPSBT() and SignPSBTInput() with a PSBTFillOptions struct.

This makes it easier to add additional options later without large code
churn, such as avoid_script_path proposed in #32857. It also makes the
use of default boolean options safer compared to positional arguments
that can easily get mixed up.
