[classlib][luni] - add cache for file's canonical path
------------------------------------------------------

                 Key: HARMONY-6200
                 URL: https://issues.apache.org/jira/browse/HARMONY-6200
             Project: Harmony
          Issue Type: Sub-task
          Components: Classlib
    Affects Versions: 5.0M9
            Reporter: Regis Xu


File.getCanonicalPath is very time cost and is heavily used by checking file permission. But
in the most of cases, the canonical path is never change, it's better to cache them to avoid
calculate every time. And I found RI also has cache: File.getCanonicalPath doesn't reflect
change in file system real-time.
