Note that this also makes it possible to move several classes
into the module-compiler.cc file and inline their implementations.
This also allows removing several uses of wasm-module.h from
other places in V8 that include wasm-objects.h.

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.

To speed up compilation times, jumbo allows files to be compiled
together. This is a well known method ("unity builds") to both
compile faster and create a poor man's "full program optimization".
We are only interested in compile times.
Background:
https://chromium.googlesource.com/chromium/src/+/master/docs/jumbo.md
Note that jumbo builds are not enabled by default. To try this out,
add use_jumbo_build=true to your GN args.

If the fuzzer input cannot be executed in the interpreter within a step
limit, then the interpreter does not calculate the result but instead
finishes with a RangeError. The problem with the input of the bug report
was that the interpreter finished with that RangeError, but the
execution of the compiled code still returned a result, which was
naturally not a RangeError and therefore caused the result check to fail.
With this CL the compiled code is not even executed when there is a
RangeError after the execution in the interpreter. Thereby we also
avoid executing an infinite loop.

This CL removes unnecessary code duplication in the fuzzer code. Instead
of having special testing functions to compile and instantiate a
WebAssembly module, we now just call SyncCompile and SyncInstantiate.
This also fixed a problem when the fuzzer generated a GrowMemory
instruction.
