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:
- meta-agl-core: remove Smack kernel patches
- meta-app-framework
- meta-pipewire/dynamic-layers/meta-app-framework/

v2: rebased
