There exist many usages of `fuzzed_data_provider` where it is evaluated directly in the function call. Unfortunately, the order of evaluation of function arguments is unspecified. This means it can differ between compilers/version/optimization levels etc. But when the evaluation order changes, the same fuzzing input will produce different output, which is bad for coverage/reproducibility. This PR fixes all these cases where by moving multiple calls to `fuzzed_data_provider` out of the function arguments.
