layout: Allow the layout to control how windows are raised in groups (#3275)

* Allow the layout to control how windows are raised in groups

Previously windows could only be focused if they weren't hidden or
were part of a group. This shifts the logic for picking the window out
of a group to the layout allowing for alternate group implementations
to function normally.

* Fix doc comment consistency

* Fix tabs in comments
