SPEC-3723: restructure meta-agl

Goal is to reach a minimal meta-agl-core as base for IVI and IC work at the same time.
Trim dependencies and move most 'demo' related recipes to meta-agl-demo.

v2: changed to bbapend + .inc , added description
v3: testbuild of all images
v4: restore -test packagegroup and -qa images, compare manifests and adapt packagegroups.
v5: rebased
v6: merged meta-agl-distro into meta-agl-core,
    due to dependency on meta-oe, moved -test packagegroup and -qa images
      to own layer meta-agl-core-test
v7: Fixed comments from Paul Barker
v8: Update the markdown files
v9: restore wayland/weston/agl-compositor recipes/appends, reworked to
    move app f/w specific changes to bbappends in meta-app-framework and
    only demo specific weston-init changes to meta-agl-demo
v10: fix s/agldemo/aglcore/ missed in weston-init.bbappend

Description:

This patch is part 1 out of 2 large patches that implement the layer rework
discussed during the previous workshop. Essentially meta-agl-core is the
small but versatile new core layer of AGL serving as basis for
the work done by the IC and IVI EGs.
All demo related work is moved to meta-agl-demo in the 2nd patchset.
This should be applied together as atomic change.

The resulting meta-agl/* follows these guidelines:
- only bsp adaptations in meta-agl-bsp
- remove the agl-profile-* layers for simplicity
-- the packagegroup-agl(-profile)-graphical and so on
   have been kept in meta-agl-demo
- meta-agl-profile-core is now meta-agl-core
- meta-agl-core does pass yocto-check-layer
-- therefore use the bbappend + conditional + .inc file
   construct found in meta-virtualization
- meta-agl/meta-security has been merged into meta-agl/meta-app-framework
- meta-netboot does pass yocto-check-layer
- meta-pipewire does pass yocto-check-layer

Migration:
All packagegroups are preserved but they're now enabled by 'agl-demo'.

+Subject: [PATCH] Smack: Handle CGROUP2 in the same way that CGROUP
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The new file system CGROUP2 isn't actually handled
+by smack. This changes makes Smack treat equally
+CGROUP and CGROUP2 items.
