        Fixed #138004 using Federico's code from #132327.

        * gtk/gtkfilesystemwin32.c (struct _GtkFileSystemWin32): Add a
        folder_hash field to keep a list of live folder objects.
        (gtk_file_system_win32_init): Create the folder_hash.
        (gtk_file_system_win32_finalize): Destroy the folder_hash.
        (gtk_file_system_win32_get_folder): Ref and return an existing
        folder if we have it around, otherwise return a new folder object.
        (struct _GtkFileFolderWin32): Add a field for the parent file system.
        (gtk_file_folder_win32_finalize): Remove the folder from the file
        system's hash table.
        (gtk_file_system_win32_create_folder):  Emit "files-added" on the
        newly-created folder's parent.  Fixes #138004.
