Adds `Fortran_COMPILER_ID` and `Fortran_COMPILER_VERSION` generator expression support to match equivalent `C_COMPILER_ID`, `CXX_COMPILER_ID`, `C_COMPILER_VERSION`, and `CXX_COMPILER_VERSION` support. This is very helpful in the case where the C/C++ compiler suite is a different type of compiler from the platform Fortran compiler and projects use generator expressions to assign compiler flags and definitions. (e.g. `GNU` C/C++ and `SunPro` Fortran on Linux)
