Start state engine and API binder in parallel

Browse Source 
The state engine and preloading is performed before the device gets a
chance to register, while this is desirable for preloaded apps, it
introduces a delay on registration which is known to cause issues since
the VPN is also trying to connect at the same time.

This triggers a simultaneous start of the device engine, the API binder
and the supevisor API to avoid delays.
