Add FSEngine FilePath Cache

To speed up file dialogs we introduce a 1 minute cache for
the FilePathInfo.

A new version of "IDevice::iterateDirectories" allows implementations to
provide the FilePathInfo directly.

DockerDevice implements fetching the filePathInfo during
iterateDirectories which greatly improves the speed again.
