feat: add RAID_TARGET_UPDATE event and GetRaidTargetIndex/SetRaidTarget

Browse source 
Fire RAID_TARGET_UPDATE event when raid markers (skull, cross, etc.)
are set or cleared on targets. Add two Lua API functions:
- GetRaidTargetIndex(unit) returns marker index 1-8 (or nil)
- SetRaidTarget(unit, index) sets marker 1-8 (or 0 to clear)

Enables raid marking addons and nameplate addons that display raid
icons to react to marker changes in real-time.
