Battle#getRelevantEffectsInner performs a lookup for the base species of
every Pokemon with ModdedDex#getEffect, then invokes callbacks. The
lookup is expensive, and callbacks very rare. In fact, there are only
ever two callbacks: one for Arceus (SwitchIn) and one for Silvally
(SwitchIn).
Instead of an expensive ModdedDex#getEffect lookup for the callbacks,
put the callbacks directly on the Pokemon's Template object.
On my machine, this commit speeds up Pokemon Showdown's tests by 20%.
