This mechanism ensures APIs like wasm async complete their work,
without requiring use of natives (%APIs).
The mechanism is similar to the one used in content_shell,
which should allow us to easily port tests in that environment.

Today, the semantics of:
WebAssembly.instantiate
and
WebAssembly.compile().then(new WebAssemblyInstance)
are subtly different, to the point where attempting the proposed
change uncovered bugs.
In the future, it's possible that .instantiate actually have different
semantics - if we pre-specialized to the provided ffi, for example.
Right now that's not the case.
This CL:
- gets our implementation closer to what developers may write using
the compile -> new Instance alternative, in particular wrt promise
creation. By reusing code paths, we uncover more bugs, and keep
maintenance cost lower.
- it gives us the response-based WebAssembly.instantiate implicitly.
Otherwise, we'd need that same implementation on the blink side. The
negative is maintenance: imagine if the bugs I mentioned could only be
found when running in Blink.
