76db420e - [libc][docs] Add nl_types.h POSIX header documentation (#122006) (#194373)

[libc][docs] Add nl_types.h POSIX header documentation (#122006) (#194373) Add nl_types.h implementation-status docs to llvm-libc. Depends on PR #194367. That change fixes docgen lookup for underscored headers, without it, the macros of nl_types.h implementation status is not reported accurately.
