Fix C++14 build with GCC 12

Browse Source 
Since adding bits/utility.h in commit e9a8c48e4f, a C++14 build with
GCC 12 (and potentially also other compiler versions) failed with
```
While building module 'Core':
While building module 'std' imported from input_line_1:1:
In file included from <module-includes>:38:
/opt/gcc/12.2.0/include/c++/12.2.0/functional:337:35: error: missing '#include <bits/utility.h>'; 'tuple_size' must be declared before it is used
      = typename enable_if<(__i < tuple_size<_Tuple>::value),
                                  ^
/opt/gcc/12.2.0/include/c++/12.2.0/bits/utility.h:49:12: note: declaration here is not visible
    struct tuple_size;
           ^
```

Apparently, once the module is declared, it must also be enabled for
C++14 and not restricted with cplusplus17.
