  Log Message:
  -----------
  [libc] Add sys/stat syscall wrappers (#195295)

Added ErrorOr-returning syscall wrappers for chmod, fchmod, fchmodat,
mkdir, mkdirat, and statx in
src/__support/OSUtil/linux/syscall_wrappers/. Migrated the sys/stat
Linux entrypoints to use them.

Added hdr/types/struct_stat.h proxy header. Updated stat, lstat, fstat
to use it, and kernel_statx to use the new statx wrapper.

Fixed fchmodat CMakeLists.txt to reference fchmodat.h (was fchmod.h).
Updated test dependencies to use hdr/sys_stat_macros.
