efl_ui_widget: optimize focus 

this commit ensures 2 things:
1. This ensures that the parent is not evaluated when there was no state
changed, this cuts down roughly 30% of the calls to full_eval
2. This ensures that we only listen to parent manager changes when we
are actaully registered. This reduces the amount spend in event emission
a lot.
