Make engine ONE_PLY value independent This non-functional change patch is a deep work to allow SF to be independent from the actual value of ONE_PLY (currently set to 1). I have verified SF is now independent for ONE_PLY values 1, 2, 4, 8, 16, 32 and 256. This patch gives consistency to search code and enables future work, opening the door to safely tweaking the ONE_PLY value for any reason. Verified for no speed regression at STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 95643 W: 17728 L: 17737 D: 60178 No functional change.
