LLVMFlang-Fortran: Use -J instead of -module-dir

Browse Source 
In flang, both -J and -module-dir support both joined and separate values. For
the -J option, these are of the form `-J<value>` and `-J <value>` respectively.
Once https://github.com/llvm/llvm-project/pull/168748 is committed, -module-dir
will only work with a separate value. Setting CMAKE_Fortran_MODDIR_FLAG to -J
ensures that both joined and separate styles will continue to work after that
change is made. As far as behavior is concerned, both -J and -module-dir are
aliases.
