move openbmc targets into this repo

OpenBMC is moving towards individual repos hosting and maintaining their
own systemd files. This allows the corresponding maintainer more control
over their systemd files and removes the meta-* layer maintainer from
needing to be involved.

The systemd targets defined and used by OpenBMC are implemented by
phosphor-state-manager code and services so move them into this
repository.

Once this is merged, its bump will need to be combined with a change in
the meta-phosphor layer that removes the target files.
