Fix Instruct bypassing AtkCanceler, Entry Hazards targeting wrong side of the field if opponent fainted

[PhallenTree]

• Fixes Instruct bypassing AtkCanceler checks (Instruct allowed the target to act while asleep, flinched, etc.) and its interaction with First Turn Only moves (Fake Out, First Impression, Mat Block).
• Also fixes Instruct's animation using the attacker and target of the called move.

Added some Instruct tests to confirm some interactions such as:

A Pokémon can successfully be instructed to repeat a move when under the effect of Torment or to use a status move while holding an Assault Vest. When instructed to use Fake Out, Mat Block, or First Impression, the target will attempt to use the move and PP will be deducted from it, but the move will fail. When instructed to use a move that would be prevented by Disable, Heal Block, Gravity, Throat Chop, Taunt, or Imprison, the target will attempt to use it, but the move will fail without PP being deducted.

The instructed move will target the same Pokémon slot as the previously used move, as long as a Pokémon is present in that slot.

Instructed moves retain their original priority, regardless of the priority of Instruct - for example, Quick Attack still fails in Psychic Terrain when Instruct is used at 0 priority to call it.

• Fixes Entry Hazards being setup on the wrong side of the field if the opponent fainted before the entry hazards being setup (happened because it would cause it to target battler = 2 or battler = 3 in Singles)
  Added the 2 tests from Sticky web is placed on the wrong side after Explosion / Memento #5259.

• Removes unused BattleScript_AuroraVeilEnds and STRINGID_AURORAVEILENDS (Aurora Veil uses BattleScript_SideStatusWoreOff)
