fuzz: Rework ConsumeScript
This should make it easier for the fuzz engine to explore multisig code
paths. See discussion in https://github.com/bitcoin/bitcoin/issues/23105
The downside is that all fuzz inputs that use ConsumeScript are now
invalidated and need to be re-generated.
Another downside may be that most multisig scripts from ConsumeScript are
using likely not fully valid pubkeys.
