Add posix_spawn_file_actions_add{f}chdir

Browse Source 
POSIX®.1-2024 now defines posix_spawn_file_actions_addchdir and
posix_spawn_file_actions_addfchdir.  Add these interfaces to spawn.h,
guarded as POSIX 202405 symbols.

Cygwin-only: Export them as aliases of the *_np counterparts. Bump
API minor.
