Andreas Haas eb64b26f8f [cleanup][wasm][fuzzer] Share code among the different fuzzers.
With this CL we share code among the wasm fuzzers which construct a
module and run it in the interpreter and as compiled code.The fuzzers
themselves only contain the code now which creates the module and the
parameters.
