Fix NNUE compatibility check to validate king count (#932)

Add safeguard in nnue_applicable() to ensure that when nnueKing is set,
both WHITE and BLACK have exactly one king of that piece type. This prevents
NNUE from being used in positions where the king count doesn't match the
expected configuration, which could lead to incorrect evaluations.
