Prepare master for new framework integration
During the last workshop the transition to the new framework was presented.
This change essentially deprecates the SMACK-based application framework.
To prepare the integration of it, we remove the deprecated components:
- recipes-apis : all agl-service-*
- recipes-demos: all demo apps but homescreen
- non-essential configurations
Todo:
We need to bring-back the html5 image in a follow-up w/o ties into the old framework.
v2: kept WAM + Chromium recipes for reference
v3: rebased
Bug-AGL: SPEC-4121
