eqcompare: numeric InventoryType lookup, drop bagtypes/itemtypes locales

Both sub-tables carried per-locale strings only so pfUI's own code could
match against localized text. ClassicAPI's numeric item APIs replace
both:

- GetBagFamily now reads classID/subClassID from C_Item.GetItemInfoInstant
  and switches on the numbers (class 1 = Container, class 11 = Quiver).
- eqcompare pulls the itemID from GameTooltip:GetItem(), fetches the
  numeric invType via C_Item.GetItemInventoryTypeByID, and looks up the
  destination slot(s) in a numeric slotTable keyed by Enum.InventoryType.
  Pair-slot invtypes (finger / trinket / one-hand weapon) list both
  destinations directly, so the "_other" string-concat hack is gone.

Removes the setglobal INVTYPE_* injection, the tooltip text scan, and
the itemtypes + bagtypes locale sub-tables across all 7 files.
