Remove dead code left over from earlier refactors The following have zero references repo-wide: Move::to_sq_unchecked() (types.h): added in 542c30c2 for a branchless correction-history update; its only caller was removed in 5ae13d2b ("Remove Redundant Branchless Execution"), leaving the method unused. PipeDeleter (misc.h): the custom deleter for the std::unique_ptr<FILE, PipeDeleter> that wrapped popen("lscpu"). That pipe was removed in c8375c2f ("On linux use sysfs instead of lscpu"), so the struct has been unused since. Dropping PipeDeleter also removes the last user of <cstdio> in misc.h, so that include is dropped as well. closes https://github.com/official-stockfish/Stockfish/pull/6948 No functional change
