Remove the dead power animation override and valid item flag code

PowersManager.AnimationOverrides was loaded from
static_power_animation_override and never read. validItemFlags on
AbstractPowerAction was always 0 and its getter had no callers; its
loader (static_power_effect_allowed_item) was already commented out.
No value change.
