Clemens Backes 18fbc33ea4 [wasm][fuzzer] Remove unused arguments
The number of arguments and their values were generated and passed by
the individual fuzzers, but were unused by the caller. Instead, default
arguments are generated in {MakeDefaultInterpreterArguments} and
{MakeDefaultArguments}.
Thus this CL removes the dead parameters and assignments.
