Add cost model parameters for lookupCoin and valueContains
- Add paramLookupCoin :: f ModelThreeArguments to BuiltinCostModelBase - Add paramValueContains :: f ModelTwoArguments to BuiltinCostModelBase Part of implementing costing for lookupCoin and valueContains builtins. Currently these functions use unimplementedCostingFun which makes them prohibitively expensive. This adds the type-level infrastructure needed for proper costing.
