LOG: [Flang] Re-enable -print-resource-dir compiler option (#96799)

This PR re-enables the command line option `-print-resources-dir` after
PR #96557 has reverted the changes made.

The way this works now, is that it simply prints the current resource
dir, which points to clang/$version.

Added: 
    flang/test/Driver/print-resource-dir.F90

Modified: 
    clang/include/clang/Driver/Options.td

Removed:
