Mircea Trofin de964dbe57 Introducing an event loop mechanism for d8.
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.
