AntennaTracker: move version to a static member

We should never include version.h or ap_version.h headers directly
on a header since this will trigger a complete rebuild of the
codebase when we commit to the repository. The ap_version.h header
is auto-generated containing information from the current commit.

If we include it in a header, every other file that ends up including
that header (directly or indirectly) will need to be rebuilt. No
ccache's cache beats having to do nothing when the header is just
not included.

version.h contains information that is kept on a struct inside
each vehicle. Rather than using the macros from each vehicle,
the getter should be preferred, which returns an AP_FWVersion
referente.
