Add GetUniquePath helper function to file_util.cc

As part of the work to support drag-and-drop of Outlook.exe emails and
attachments to a Chromium drop target:

https://chromium-review.googlesource.com/c/chromium/src/+/1487798/1

common code to get a unique file path was found. It was suggested in
that code review that the implementation of the helper function GetUniquePath
be put in a separate pull request.  The helper is now used in
three places that had the same logic depending on GetUniquePathNumber,
and the helper will be also used in the change above.
