keyboard: Only rebuild keyboard actor on keyboard type changes

Browse Source 
About every other situation can do with synchronizing keyboard visibility,
and keyboard layout changes are already handled internally in the Keyboard
object.

A downside of this approach is that once created, there will always be a
Keyboard instance and its full actor hierarchy. Seems reasonable to do that
since we can't tell it won't ever be needed.
