This fixes the error message generated for compile errors during
asynchronous instantiation. It shows "WebAssembly.instantiate()" now
instead of "WebAssembly.compile()".

The problem was that in AsyncCompileJob::FinishModule we allocate a
handle, but when this function is called from streaming compilation, then
there was no HandleScope around AsyncCompileJob::FinishModule. This issue
was fixed in another CL, https://crrev.com/c/1172357. This CL is just a
rebase of the original CL.

This CL introduces a set of configuration options implemented as
a struct of booleans that together comprise the set of enabled
or detected features. The configuration options replace command-line
flags that were checked deep in the implementation. As such, it is
necessary to plumb them through multiple levels of abstraction.

At the moment, WebAssembly.instantiate(bytes) is implemented by
desugaring it to WebAssembly.compile(bytes).then(WebAssembly.instantiate).
The problem is that the {then} in this snippet is observable. With this
CL I introduce a CompilationResultResolver which allows to do the
desugaring internally and thereby make the {then} unobservable.
Unfortunately the result of WebAssembly.instantiate(bytes) is different
than the result of WebAssembly.instantiate(module). Therefore I also
introduced an InstantiationResultResolver for symmetry with
WebAssembly.compile.

There is no good reason to have the meat of most objects' initialization
logic in heap.cc, all wrapped by the CALL_HEAP_FUNCTION macro. Instead,
this CL changes the protocol between Heap and Factory to be AllocateRaw,
and all object initialization work after (possibly retried) successful
raw allocation happens in the Factory.
This saves about 20KB of binary size on x64.

This is a further step to separate the implementation of the JavaScript
API from the internals of the WASM implementation. Now, wasm-js.cc
only needs to interact with the WASM engine and is (almost) independent
of module-decoder.h and module-compiler.h.
Also, move SyncCompileAndInstantiate() into wasm-module-runner.cc.

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.
