QtAsyncio: Add wrapper for calls in executor

Executors require a bit of extra work for QtAsyncio, as we can't use
naked Python threads, instead we must make sure that the thread created
by executor.submit() has an event loop. This is achieved by submitting a
small wrapper that attaches a QEventLoop to the executor thread, and
then creates a singleshot timer to push the actual function for the
executor into this new event loop.
