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`.
Split Windows.Storage.ApplicationData definitions out of windows.storage.idl to windows.storage.applicationdata.idl and import that instead of whole window.storage.idl into windows.storage.applicationdata.dll, to better reflect Windows implementation.
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 https://gitlab.winehq.org/wine/wine/-/merge_requests/8394
