SPEC-3723: restructure meta-agl-demo

All demo related components should be in here now.

We keep the packagegroups on purpose for now to stay backward-compatible.

v2: layer does pass yocto-check-layer, dependencies adapted
v3: remove the dynamic-layer setup, use all-in-one approach
v4: Fixed comments from Paul Barker. Tnx!
v5: Removed wayland/weston/agl-compositor additions, except for demo
    specific weston-init bbappend

Follow-up changes required later:
      - massaging packagegroups
      - scrub of recipes

+Subject: [PATCH] Set webapp roles that are max 12 characters long.
+
+From: =?UTF-8?q?Jacobo=20Aragunde=20P=C3=A9rez?= <jaragunde@igalia.com>
+
+This is a workaround for SPEC-3127. To prevent repeated roles as much
+as possible, I'm using the appid as a basis instead of "Webapp-" +
+host + port, which has many chances to be redundant in the first 12
+chars.
