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

[Petter Berntsson via libc-commits]

https://github.com/petbernt created https://github.com/llvm/llvm-project/pull/194373

Add nl_types.h implementation-status docs to llvm-libc.

Depends on PR #194367. That change fixes docgen macro lookup for underscored headers, without it, the macros of nl_types.h implementation status is not reported accurately.
