[build-system] Fix gfortran macros

Some macros are not compatible with gfortran built-in preprocessor. This MR aims to fix these issues.

Why do we need this

This is part of a series of fixes that would get rid of the cpp workflow and simplify the build procedures. This is especially needed to build a simple cmake buildchain

Checklist

• I have checked that my code follows the Octopus coding standards
• I have added tests for all the new features added in this request.

• c5d672fd - Fix gfortran macros

Compare with previous version

There's a more general problem here, which is the lack of standard Fortran preprocessor. Since we aim at supporting more than gfortran, the CMake build system must also work with other compilers, like the Intel one. Any ideas how to tackle this? Also, is there a reason why we can't use cpp with CMake?

assigned to @LecrisUT

Currently there is still an issue with converting the \newline to actual newline characters from global.h without using the perl script. If we can do that then, we can eliminate preprocess.pl from the cmake workflow
