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.

This fixes a long-standing TODO to only make a copy of a module's
wire bytes if the input is a SharedArrayBuffer and also fixes the
concurrent-modification bug for synchronous validation.

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.
