feat: add party/raid unit IDs and game events for Lua addon system

Browse source 
Extend resolveUnit() to support party1-4, raid1-40, and use resolveUnitGuid
for UnitGUID/UnitIsPlayer/UnitBuff/UnitDebuff (including unitAurasCache for
party member auras). Fire UNIT_HEALTH, UNIT_POWER, UNIT_AURA, UNIT_SPELLCAST_START,
UNIT_SPELLCAST_SUCCEEDED, GROUP_ROSTER_UPDATE, and PARTY_MEMBERS_CHANGED events
to Lua addons from the corresponding packet handlers.
