build: Introduce DEFAULT_APP with automatic builds

Browse source 
Introduce the Makefile variable DEFAULT_APP which should be the path
to the device app binary to include in the obliagory slot 0.

Build automatically: the default app, the new digest file
mgmt_app_digest.h for the firmware which contains the digest of
DEFAULT_APP, the default partition table, and all the tools necessary
to generate this.
