Most things are moved unchanged. The relatively few changes are to the
documentation, as the split between the meta-ohos and manifest is gone,
as well as to the actual CI definitions for the workspace directory,
since the sources/ sub-directory is gone, and there was some
backwards-compatibility code that no longer makes sense to maintain.

used as foundation for the set of :doc:`shared jobs <../shared-jobs>`. Hidden
jobs do not participate in any pipeline directly. They can only be used as
templates, using the extends: ... mechanism, to share and reuse
implementation details.
