feat: add GetSpellInfo, GetSpellTexture, GetItemInfo and more Lua API functions

Browse source 
Add spell icon path resolution via SpellIcon.dbc + Spell.dbc lazy loading,
wired through GameHandler callback. Fix UnitBuff/UnitDebuff to return icon
texture paths instead of nil. Add GetLocale, GetBuildInfo, GetCurrentMapAreaID.
