Add suggestions to autocomplete the model fields

When I discussed the export control with Tino Nesslinger, I realized that we have a lot of autocompletion/suggestion fields for the device basic data, but none for the model.

Regarding that we want to connect the export control information with the combination out of manufacturer and model, it would help to have there the auto completion too (and for the platform model as well).

Bonus point would be to take the manufacturer into account, as the model entries are usually specific to their manufacturers.
