Expand description

Assigns capture scores for moves by filling move_scores array with moves_count length (starting from start_index), based on current context. If transposition table move is available, it’s passed as tt_move too. Moves are prioritized as follows (from most important to the less ones):

for transposition table move, assign MOVE_ORDERING_HASH_MOVE
for every positive capture, assign SEE score + MOVE_ORDERING_WINNING_CAPTURES_OFFSET
for every negative capture, assign SEE score + MOVE_ORDERING_LOSING_CAPTURES_OFFSET
