[Driver] Don't add -dwarf-column-info when using -gcodeview on non-msvc targets

-dwarf-column-info is omitted if -gcodeview is specified for msvc
targets at the moment, but since -gcodeview is an option that can be
specified for any target, there's little reason to restrict this
handling to msvc targets.

This allows getting proper codeview debug info by passing -gcodeview
for e.g. MinGW targets as well.
