Use freedesktop/ci-templates for the GitLab CI

The CI templates include infrastructure to create docker images with all
packages specified in tools/ci-install.sh. Using those docker images
speeds up the CI since we don't have to install all the dependencies in
every pipeline. We could extend this to also create containers that have
mingw pre-installed but for now we only create an image with the
dependencies that are required for every job.
