Expand statistics tools for engine development This patch adds more debugging slots up to 32 per type and provide tools to calculate standard deviation and Pearson's correlation coefficient. However, due to slot being 0 at default, dbg_hit_on(c, b) has to be removed. Initial idea from snicolet/Stockfish@d8ab604 closes https://github.com/official-stockfish/Stockfish/pull/4354 No functional change
