Add helpers for managing aligned memory Previously, we had two type aliases, LargePagePtr and AlignedPtr, which required manually initializing the aligned memory for the pointer. The new helpers: - make_unique_aligned - make_unique_large_page are now available for allocating aligned memory (with large pages). They behave similarly to std::make_unique, ensuring objects allocated with these functions follow RAII. The old approach had issues with initializing non-trivial types or arrays of objects. The evaluation function of the network is now a unique pointer to an array instead of an array of unique pointers. Memory related functions have been moved into memory.h Passed High Hash Pressure Test Non-Regression STC: https://tests.stockfishchess.org/tests/view/665b2b36586058766677cfd2 LLR: 2.93 (-2.94,2.94) <-1.75,0.25> Total: 476992 W: 122426 L: 122677 D: 231889 Ptnml(0-2): 1145, 51027, 134419, 50744, 1161 Failed Normal Non-Regression STC: https://tests.stockfishchess.org/tests/view/665b2997586058766677cfc8 LLR: -2.94 (-2.94,2.94) <-1.75,0.25> Total: 877312 W: 225233 L: 226395 D: 425684 Ptnml(0-2): 2110, 94642, 246239, 93630, 2035 Probably a fluke since there shouldn't be a real slowndown and it has also passed the high hash pressure test. closes https://github.com/official-stockfish/Stockfish/pull/5332 No functional change
