Modules: Factor out helpers for GNU language standard flags
Add the following macros to `${CMAKE_ROOT}\Modules\Compiler\GNU.cmake`:
* `__compiler_gnu_c_standards()`
* `__compiler_gnu_cxx_standards()`
These macros are used to define the
`CMAKE_<LANG><STANDARD>_STANDARD_COMPILE_OPTION` and
`CMAKE_<LANG><STANDARD>_EXTENSION_COMPILE_OPTION` variables for C-
and C++-based languages for GCC. The macros are similar to the
existing `__compiler_clang_cxx_standards()` macro found in
`${CMAKE_ROOT}\Modules\Compiler\Clang.cmake`.
