No touch handles when Views textfield cannot get focused
Whenever a Views textfield is going to show touch handles, it should
first check that it has focus or not. If not, the handles should not be
shown. This might be because the textfield is disabled or it is
explicitly set to be non-focusable, among other reasons.
