This is needed because in `master`, the `gitlab:assets:compile` is
created, but not the `gitlab:assets:compile pull-cache` job, and the
`needs` keyword cannot take jobs that don't exist, thus we have to
create a dedicated job for `master`, with `needs: ["build-qa-image",
"gitlab:assets:compile"]` instead of `needs: ["build-qa-image",
"gitlab:assets:compile pull-cache"]`.

This also makes 'package-and-qa-manual' created for 'master' because
it's a valid use-case to run manual QA on 'master'.

Without this change, no pipeline could be created for auto-deploy
branches due to the following error:

    The form contains the following error:
    package-and-qa-manual: needs 'build-qa-image'

Don't use ee/.gitlab/ for CI config files

See merge request gitlab-org/gitlab-ce!32351

Make sast & dast artifacts browseable

See merge request gitlab-org/gitlab-ce!32219

These files are not available in CE, resulting in CI pipeline failures
when trying to include these files. Since the job is already configured
to only run on EE, we can just include it in both CE and EE.
