Fortran: Add infrastructure to detect compiler version (#15372)
Fortran does not offer syntax to compose a string literal at
preprocessing time from numeric compuations. Instead encode each digit
of each component as a separate INFO string and compose them in CMake
code after extraction. Support MAJOR, MINOR, PATCH, and TWEAK
components with up to 8 digits each.
