[libc] Add `returns_twice` attribute to `setjmp(3)` (#124370)
This is to ensure that calls to `setjmp(3)` result in correct code
generation that respects `setjmp(3)`'s `returns_twice` behavior.
Otherwise, we might run into bugs (for example, Clang may perform
tail-call optimization on this function if `-fno-builtins` is set
(#122840)).
