Rakhim Khismet 26d105565f [fuzzer] Add struct type and array type to fuzzed module
We add a struct type and array type to the fuzzed module.
Since the interpreter does not support wasm-gc,
we only do so if liftoff is used as a reference implementation.
Also, adding liftoff parameter to all GenerateModule definitions.
