Pekka Paalanen b3ba1becba libweston: remove fbdev backend 
Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.

Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.

I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.

Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

# This file uses the freedesktop ci-templates to build Weston and run our
# tests in CI.
#
# ci-templates uses a multi-stage build process. First, the base container
# image is built which contains the core distribution, the toolchain, and
# all our build dependencies. This container is aggressively cached; if a
# container image matching $FDO_DISTRIBUTION_TAG is found in either the
# upstream repo (wayland/weston) or the user's downstream repo, it is
# reused for the build. This gives us predictability of build and far
# quicker runtimes, however it means that any changes to the base container
# must also change $FDO_DISTRIBUTION_TAG. When changing this, please use
# the current date as well as a unique build identifier.
#
# After the container is either rebuilt (tag mismatch) or reused (tag
# previously used), the build stage executes within this container.
#
# The final stage is used to expose documentation and coverage information,
# including publishing documentation to the public site when built on the
# main branch.
#
# Apart from the 'variables', 'include', and 'stages' top-level anchors,
# everything not beginning with a dot ('.') is the name of a job which will
# be executed as part of CI, unless the rules specify that it should not be
# run.
#
# Variables prefixed with CI_ are generally provided by GitLab itself;
# variables prefixed with FDO_ and templates prefixed by .fdo are provided
# by the ci-templates.
#
# For more information on GitLab CI, including the YAML syntax, see:
# https://docs.gitlab.com/ee/ci/yaml/README.html
#
# Note that freedesktop.org uses the 'Community Edition' of GitLab, so features
# marked as 'premium' or 'ultimate' are not available to us.
