Remove the dead static_rune_baseeffect path

RuneBaseEffect, its handler, every effectsGranted field and getter (including
the PromotionClass promoID*10+2500..2503 lookups) and the empty
PlayerBonuses.grantEffect had no reader (2.10a). The GameObjectType constant
stays so later ordinals are unchanged. No value changes.
