tests/stacking: Add a multi-monitor stacking test

New add_monitor command for adding secondary monitors. Support setting
the workspaces-only-on-primary preference.

The stacking test tests the focus and stacking for multiple monitors
with workspaces-only-on-primary=true. The default_focus changes
previously broke this.
