Introduce container_is_scratchpad_hidden

Just a convenience function that improves readability of the code.

Other things worth noting:

* container_get_siblings and container_sibling_index no longer use the
const keyword
* container_handle_fullscreen_reparent is only ever called after
attaching the container to a workspace, so its con->workspace check has
been changed to an assertion
