model: Add tracking of our own static config versions

Currently our static configs don't directly support updates.
(They really should)

We also have a use case around simply introspecting the state
that static configs were enabled (xref ostreedev/ostree#3150)
where we want to have ostree not run grub2-mkconfig in this case.

In preparation for both of these things, add tracking of
our *own* version of the static configs into the metadata.

In theory of course, static configs could include other components
(ignition, greenboot, etc.) and we should track those too.  For
now this at least gets us basic metadata.
