feat: add UnitIsTapped, UnitIsTappedByPlayer, UnitIsTappedByAllThreatList

Browse source 
Add three tapped-state query functions for addons:
- UnitIsTapped(unit): true if any player has tagged the mob
- UnitIsTappedByPlayer(unit): true if local player can loot (tapped+lootable)
- UnitIsTappedByAllThreatList(unit): true if shared-tag mob

Used by nameplate addons (Plater, TidyPlates) and unit frame addons
to determine and display tap ownership state.
