Makefiles: Factor out makefile target path escaping and quoting

Code paths that write makefile target paths use a combination of
`cmSystemTools::ConvertToOutputPath` and `cmMakeSafe`.  Some were
missing the latter.  Wrap these two steps up into a dedicated
`ConvertToMakefilePath` method provided on both the local and global
generators.
