tuklib: Update tuklib_attr_noreturn for C11/C17 and C23.
This makes no difference for GCC or Clang as they support
GNU C's __attribute__((__noreturn__)) but this helps with MSVC:
- VS 2019 version 16.7 and later support _Noreturn if the
options /std:c11 or /std:c17 are used. This gets handled
with the check for __STDC_VERSION__ >= 201112.
- When MSVC isn't in C11/C17 mode, __declspec(noreturn) is used.
C23 will deprecate _Noreturn (and <stdnoreturn.h>)
for [[noreturn]]. This commit anticipates that but
the final __STDC_VERSION__ value isn't known yet.
