qpa: Remove QPlatformDialogHelper::deleteNativeDialog()

This function isn't really needed. The QDialogPrivate destructor deletes
the platform helper, so the QDialog destructor does not need to do it.
Subclasses of QPlatformDialogHelper are now responsible for deleting any
native resources they create.

The one place in QFileDialog that needs to recreate the native dialog
can simply recreate the helper. QDialogPrivate::deleteNativeDialog() now
becomes QDialogPrivate::deletePlatformHelper(), which resets all state
to allow the platform helper to be recreated.
