Remove third compare tooltip support

Drop legacy third shopping tooltip handling from GameTooltip_ShowCompareItem. Unpack only two shoppingTooltips, remove unused item3/shoppingTooltip3 variables and commented code, and simplify anchor/owner logic for the two-compare layout. GAP/backdrop spacing calculation is preserved.
