The wasm-async fuzzer uses the bytes provided by the fuzzer engine
directly as wasm module bytes, compiles them with async compilation, and
then tries to execute the "main" function of the module. This "main"
can have an infinite loop which causes a timeout in the fuzzer. With
this CL the "main" function is first executed with the interpreter. If
the execution in the interpreter finishes within 16k steps, which means
that there is no infinite loop, also the compiled code is executed.
I added the raw fuzzer input as a test case because in this case I
really want to test the fuzzer and not V8.

This allows to reuse the class e.g. in the baseline compiler.

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.
