Read defense, bulk and primary attr from the cache ItemTemplate

item_defense_rating, item_bulk_factor and item_primary_attr are
Item-only fields, not on CObjectTemplate, so their consumers read
engine.parsers.objects.ItemTemplate._items by templateID, like the
RuneTemplate and DeedTemplate consumers. The primary attr checks
compare with == because the cache template leaves the attr null
(legacy: None) on non-weapons.

Parity (offline, scripts/p14.py, 7586 templates): 0 differences in
item_defense_rating, item_bulk_factor and item_primary_attr. Every DB
ARMOR and WEAPON template is in the ITEM folder, so both sides gate
these fields on the same templates. No value changes expected.
