view: add client_request flag to view->impl->unmap()

Browse source 
This makes explicit the subtle behavioral difference between
xwayland_view_unmap() and handle_unmap().

With this change, the XDG and XWayland versions of handle_map/unmap()
are now identical, which will make further refactoring possible.
