bar_cmd_modifier: add support for none

sway-bar(5) documents `modifier none`, which comes from i3. This
implements the functionality for `modifier none` since it was not
previously implemented. The bar modifier toggles visibility of the bar
when the bar mode is set to hide. When the bar modifier is set to
`none`, the ability to toggle visibility of the bar will be disabled.
