Read item_type through the cache template bridge

Every consumer of the legacy ItemTemplate item_type now reads
template.cacheTemplate.getItemType(). Left on the legacy field: the
type count in dbItemHandler.LOAD_ITEM_TEMPLATES, which runs before the
bridge is linked. The charter checks already read DeedTemplate.

Parity (offline, static_item_templates vs the template
CObjectIndex.lookup picks, scripts/p14.py, 7586 templates: ITEM 4011,
DEED 880, RUNE 2695): 0 differences in item_type. No value changes
expected.
