Completes the pret/pokefirered parity for wild encounter rate gating,
on top of the cooldown port in b84c2c15.

Ports DoWildEncounterRateTest as Encounters.encounterRate(): *16, bike
*80/100, banked failure rate +buff*16/200, flute, Cleanse Tag *2/3,
ability (Stench /2, Illuminate *2), then the 1600 clamp last -- pret's
exact order, which the modifier-order tests pin down.

Ports AddToWildEncounterRateBuff: a failed rate test (or a rate test
that passes but picks no slot) banks the area rate; an active Repel
zeroes the bank. Without this, encounters were still flat-rate rather
than ramping after near-misses.

Also ports the Mach/Acro bike *80/100 modifier.

End-to-end goldens on Route 1 (rate 21, 4000 steps) shift 397->401
with the cooldown and 843->858 without. That matches pret's steady
state analytically: a 6-step cooldown followed by p~0.112 as the bank
ramps gives a cycle of (1-0.94^6)/0.112+6 ~ 10.3 steps, ~10%/step.
The observed 401/4000 = 10.03% confirms it.

tests/game3_rng_test.lua now resets rate modifiers per replay, since
the banked rate makes sequences history-dependent; a map load resets
in-game.
