Fix Wind Rider boosting stat everytime AI's moveset is calculated

[LaukkaE]

Wind Rider boosted attack everytime AI's moveset was calculated, even multiple stages per turn.

Thanks for fixing this for me. While you're here, do you mind adding the on summon effect of wind rider? Full functionality would also mean changes in the Tailwind onAdd but here should be all the code to be added on the ability side of things.

export class PostSummonStatChangeOnArenaAbAttr extends PostSummonStatChangeAbAttr {
  private tagType: ArenaTagType;
  constructor(tagType: ArenaTagType) {
    super([BattleStat.ATK], 1, true, false);
    this.tagType = tagType;
  }

  applyPostSummon(pokemon: Pokemon, passive: boolean, args: any[]): boolean {
    if (pokemon.scene.arena.getTag(this.tagType)) {
      return super.applyPostSummon(pokemon, passive, args);
    }
    return false;
  }
}

  new Ability(Abilities.WIND_RIDER, 9)
    .attr(MoveImmunityStatChangeAbAttr, (pokemon, attacker, move) => pokemon !== attacker && move.getMove().hasFlag(MoveFlags.WIND_MOVE), BattleStat.ATK, 1)
    .ignorable()
    .attr(PostSummonStatChangeOnArenaAbAttr, ArenaTagType.TAILWIND)
    .partial(),

Could you fix the merge conflicts? Then this should be good to go.
