Give focus and input focus at the same time

Give focus and input focus at the same time

Currently, dali has two different focus. KeyboardFocus/KeyInputFocus.
But in other framework, they works as one focus.

Two different DALi focus will be worked as one focus via making KeyboardFocusManager give KeyInputFocus to focused control.

Plus, this patch will change focus moving behavior at text controls.
To solve this problem, make text-controller determine whether this text control will lose focus or not.
