Port Linux shared memory to BSDs and macOS Passed stc: LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 13536 W: 3564 L: 3299 D: 6673 Ptnml(0-2): 20, 1334, 3810, 1569, 35 https://tests.stockfishchess.org/tests/view/6a6dac3ac054e285ae029b30 Pretty straightforward port. Just need to work around the lack of close-on-exec in various places and replace `memfd_create` with a tempfile/unlink. Notably on macOS, `tmp` is disk backed (it's a symlink to `/private/tmp`), so this temporarily takes up ~110 MB of disk space, but it's unlikely that anything will actually be written to disk. closes https://github.com/official-stockfish/Stockfish/pull/7016 No functional change
