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'.

+# Machine Selection
+#
+# You need to select a specific machine to target the build with. There are a selection
+# of emulated machines available which can boot and run in the QEMU emulator:
+#
+#MACHINE ?= "qemuarm"
+#MACHINE ?= "qemuarm64"
+#MACHINE ?= "qemumips"
+#MACHINE ?= "qemumips64"
+#MACHINE ?= "qemuppc"
+#MACHINE ?= "qemux86"
+#MACHINE ?= "qemux86-64"
+#
+# There are also the following hardware board target machines included for
+# demonstration purposes:
+#
+#MACHINE ?= "beaglebone-yocto"
+#MACHINE ?= "genericx86"
+#MACHINE ?= "genericx86-64"
+#MACHINE ?= "edgerouter"
+#
+# This sets the default machine to be qemux86-64 if no other machine is selected:
+MACHINE ??= "qemux86-64"
+
+#
+# Where to place downloads
+#
+# During a first build the system will download many different source code tarballs
+# from various upstream projects. This can take a while, particularly if your network
+# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
+# can preserve this directory to speed up this part of subsequent builds. This directory
+# is safe to share between multiple builds on the same machine too.
+#
+# The default is a downloads directory under TOPDIR which is the build directory.
+#
+#DL_DIR ?= "${TOPDIR}/downloads"
+
+#
+# Where to place shared-state files
+#
+# BitBake has the capability to accelerate builds based on previously built output.
+# This is done using "shared state" files which can be thought of as cache objects
+# and this option determines where those files are placed.
+#
+# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
+# from these files if no changes were made to the configuration. If changes were made
+# to the configuration, only shared state files where the state was still valid would
+# be used (done using checksums).
+#
+# The default is a sstate-cache directory under TOPDIR.
+#
+#SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
+
+#
+# Where to place the build output
+#
+# This option specifies where the bulk of the building work should be done and
+# where BitBake should place its temporary files and output. Keep in mind that
+# this includes the extraction and compilation of many applications and the toolchain
+# which can use Gigabytes of hard disk space.
+#
+# The default is a tmp directory under TOPDIR.
+#
+#TMPDIR = "${TOPDIR}/tmp"
+
+#
+# Default policy config
+#
+# The distribution setting controls which policy settings are used as defaults.
+# The default value is fine for general Yocto project use, at least initially.
+# Ultimately when creating custom policy, people will likely end up subclassing
+# these defaults.
+#
+DISTRO ?= "poky"
+# As an example of a subclass there is a "bleeding" edge policy configuration
+# where many versions are set to the absolute latest code from the upstream
+# source control systems. This is just mentioned here as an example, its not
+# useful to most new users.
+# DISTRO ?= "poky-bleeding"
+
+#
+# Package Management configuration
+#
+# This variable lists which packaging formats to enable. Multiple package backends
+# can be enabled at once and the first item listed in the variable will be used
+# to generate the root filesystems.
+# Options are:
+#  - 'package_deb' for debian style deb files
+#  - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
+#  - 'package_rpm' for rpm style packages
+# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
+# We default to rpm:
+PACKAGE_CLASSES ?= "package_rpm"
+
+#
+# SDK target architecture
+#
+# This variable specifies the architecture to build SDK items for and means
+# you can build the SDK packages for architectures other than the machine you are
+# running the build on (i.e. building i686 packages on an x86_64 host).
+# Supported values are i686 and x86_64
+#SDKMACHINE ?= "i686"

+#
+# Extra image configuration defaults
+#
+# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
+# images. Some of these options are added to certain image types automatically. The
+# variable can contain the following options:
+#  "dbg-pkgs"       - add -dbg packages for all installed packages
+#                     (adds symbol information for debugging/profiling)
+#  "src-pkgs"       - add -src packages for all installed packages
+#                     (adds source code for debugging)
+#  "dev-pkgs"       - add -dev packages for all installed packages
+#                     (useful if you want to develop against libs in the image)
+#  "ptest-pkgs"     - add -ptest packages for all ptest-enabled packages
+#                     (useful if you want to run the package test suites)
+#  "tools-sdk"      - add development tools (gcc, make, pkgconfig etc.)
+#  "tools-debug"    - add debugging tools (gdb, strace)
+#  "eclipse-debug"  - add Eclipse remote debugging support
+#  "tools-profile"  - add profiling tools (oprofile, lttng, valgrind)
+#  "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
+#  "debug-tweaks"   - make an image suitable for development
+#                     e.g. ssh root access has a blank password
+# There are other application targets that can be used here too, see

+#   - 'image-prelink' in order to prelink the filesystem image

+# NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended

+
+#
+# Runtime testing of images
+#
+# The build system can test booting virtual machine images under qemu (an emulator)
+# after any root filesystems are created and run tests against those images. It can also
+# run tests against any SDK that are built. To enable this uncomment these lines.
+# See classes/test{image,sdk}.bbclass for further details.

+# can launch an interactive shell. It needs to do this since the build is
+# multithreaded and needs to be able to handle the case where more than one parallel
+# process may require the user's attention. The default is iterate over the available
+# terminal types to find one that works.
+#
+# Examples of the occasions this may happen are when resolving patches which cannot
+# be applied, to use the devshell or the kernel menuconfig
+#
+# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none

+# of the build. The reason for this is that running completely out of space can corrupt

+# cache locations to check for the shared objects.
