Pull request description:
The wallet currently estimates the size of a signed input by doing a dry run of the signing logic. This is unnecessary since all outputs we can sign for can be represented by a descriptor, and we can derive the size of a satisfaction ("signature") directly from the descriptor itself.
In addition, the current approach does not generalize well: dry runs of the signing logic are only possible for the most basic scripts. See for instance the discussion in #24149 around that.
This introduces a method to get the maximum size of a satisfaction from a descriptor, and makes the wallet use that instead of the dry-run.
