lib/defines.h: Add NORETURN attribute macro

Browse Source 
We could use the standard (C11) _Noreturn qualifier, but it will be
deprecated in C23, and replaced by C++'s [[noreturn]], which is
compatible with the GCC attribute, so let's directly use the attribute,
and in the future we'll be able to switch to [[]].
