Translate Opportunist, Aggressive and Risky trainer AI

Add the AI_Opportunist, AI_Aggressive and AI_Risky scoring layers with
the ROM's stall, reckless and risky tables, HP thresholds, last-wins
ties and strict knockout test. AIDamageCalc is ported as a
pre-variation damage estimate, including a critical-hit flag left over
from an earlier move, which the original also reads. Smart remains the
only refused layer, so the rival stays gated.
