Simplify Square Clipped ReLU code. Squared numbers are never negative, so barring any wraparound there is no need to clamp to 0. From reading the code, there's no obvious way to get wraparound, so the entire operation can be simplified away. Updated original truncated code comments to be sensible. Verified by running ./stockfish bench 128 1 24 and by the following test: STC: https://tests.stockfishchess.org/tests/view/64da4db95b17f7c21c0eabe7 LLR: 2.94 (-2.94,2.94) <-1.75,0.25> Total: 60224 W: 15425 L: 15236 D: 29563 Ptnml(0-2): 195, 6576, 16382, 6763, 196 closes https://github.com/official-stockfish/Stockfish/pull/4751 No functional change
