pokered plays no 'pitched-down faint cry': the player mon's faint is its
ordinary species cry (RemoveFaintedPlayerMon -> PlayCry) with no
Faint_Fall, and the enemy faint plays no species cry at all -- trainer
battles get SFX_FAINT_FALL then SFX_FAINT_THUD, wild battles go straight
to the victory music (FaintEnemyPokemon core.asm:732-796).
The port played the species cry AND Faint_Fall on every faint, so a
fainted enemy sounded its full battle cry and a fainted player mon got
the fall whistle the hardware never plays.
BattleState.onFaint now:
- player: Sound.playCry only
- enemy trainer: Faint_Fall then Faint_Thud (after the slide)
- enemy wild: no faint sfx (victory music already queued)
Adds tests/parity_faint_cry_bug709.lua asserting the per-side sequence.
