windows.storage: Split ApplicationData
Windows registry keys such as HKEY_LOCAL_MACHINE\\Software\\Microsoft\\WindowsRuntime\\ActivatableClassId\\Windows.Storage.ApplicationData indicate that Windows.Storage.ApplicationData related classes should be in windows.storage.applicationdata.dll, and the remaining classes together with Windows.Storage.StorageFile should be in windows.storage.dll.
This allows future implementions of class Windows.Storage.StorageFile to be correctly put in the windows.storage.dll, instead of windows.storage.applicationdata.dll, see !8394
