Summary
-------

New API method was added to query shortcut panel entries for JFileChooser, since ShellFolder is internal class which is not publicly accessible.
 
Problem
-------

ShellFolder is an internal class, and customers do not currently have a way of querying the default shortcut files on Windows, without exporting this class at compile time.

Solution
--------

Solution is to add a new api in javax.swing.filechooser.FileSystemView.java, which can be directly used.

Specification
-------------

Signatures of the api being added and the one for which the documentation is being updated in that order:

        /**
         * Returns an array of files representing the values which will be 
         * shown in the file chooser shortcuts panel.
         *
         * @return an array of {@code File} objects. The array returned may be possibly empty
         * if there are no appropriate permissions.
         * @since 12
         */
        final public File[] getChooserShortcutPanelFiles() 
    
    
        /**
         * Returns an array of files representing the values which will be shown
         * in the file chooser selector
         *
         * @return an array of {@code File} objects. The array returned may be
         * possibly empty if there are no appropriate permissions.
         * @since 9
