feat: add GetInventorySlotInfo for PaperDollFrame and BankFrame

Browse source 
Maps WoW equipment slot names (e.g. "HeadSlot", "MainHandSlot") to
inventory slot IDs, empty-slot textures, and relic check flags.
Supports case-insensitive matching with optional "Slot" suffix stripping.

Unblocks PaperDollFrame.lua and BankFrame.lua which call this function
to resolve slot button IDs during UI initialization.
