[libc] fix clang-tidy llvm-header-guard warnings (#82679) Towards the goal of getting `ninja libc-lint` back to green, fix the numerous instances of: warning: header guard does not follow preferred style [llvm-header-guard] This is because many of our header guards start with `__LLVM` rather than `LLVM`.

[libc] Add `FILENO` related macros to `unistd.h`. (#124688) Closes #124637.
