Drop `ScoreParams` in bindings builds

Drop `ScoreParams` in bindings builds

Sadly, we can't realistically expose associated types in bindings -
not only does C not have any concept of generics or associated
types (duh), but many of the downstream languages we support don't
either.

Instead, we hard-code the scoring parameters type to
`ProbabilisticScoringFeeParams` for all scorers.
