Fortran: Save frontend variant persistently for IntelLLVM
Since !5594 (merged), our IntelLLVM compiler support populates CMAKE_Fortran_COMPILER_FRONTEND_VARIANT
. However, the frontend variant was not stored in CMakeCompilerFortran.cmake
.
Backport: release
Topic-rename: IntelLLVM-Fortran-frontend-variant
