Bug 19023 - inventory tool performance

Inventory tool performance seems to be worst since 16.11.
I think it is because of authorized values computing changed by Bug 17249.

For each subfield of each item, we try to get the authorized value description
with Koha::AuthorisedValues->search_by_marc_field.
But this method does not use cache like
Koha::AuthorisedValues->get_description_by_koha_field.

I propose to use Koha::AuthorisedValues->get_description_by_koha_field and also
to look for authorized value description only for item fields used in TT :
location, notforloan, itemlost, damaged, withdrawn.

I have experimented inventory time on 100 items from 5s to 1s.

Test plan :
- Without patch
- Perform inventory with barcode file
- Check results and mesure execution time
- Apply patch
- Reperform inventory with same barcode file
- Check results is the same
- Compare execution time
- Run prove t/db_dependent/Items/GetItemsForInventory.t
