Remove LGBs from degraded loadouts without TGPs.

This only takes effect for default loadouts. Custom loadouts set from
the UI will allow LGBs. In the default case there will not be buddy-lase
coordination so we should take iron bombs instead.

Also adds single/double Mk 83 and Mk 82 weapon data to accomodate this.
