[Bug fortran/38259] New: Add version number to .mod file

[burnus at gcc dot gnu dot org]

Currently, there are only strange parenthesis-related error messages given if
an old, incompatible .mod file is used with a newer compiler, e.g.

Fatal Error: Reading module mmm at line 16 column 65: Expected left parenthesis

(cf. also PR 38248). The solution is to add a version number which is always
bumped if a .mod related change happened, which presumably was the case for all
new GCC/gfortran releases.

Could come in handy, especially if people start to distribute module files.

Jakub and Richard proposed on #gcc that this feature should still go into 4.4,
I agree.

The patch is pre-approved. (I personally had started with version 1 instead of
0, but it really doesn't matter.)
