Draft: .oniro-ci,gitlab-ci.yml: add support for publishing bundles to hawkbit

This patch-set fixes several issues and inefficiencies related to bundle build process, and starts publishing Raspberry Pi 4 builds to HawkBit. It needs to run on a protected branch for the publishing to take effect, since this unlocks protected variables with hawkbit location and credentials.
