Leanback: Accessiblity navigation fix

1. disable accessiblity focus of header view in the RowsFragment
because the focusfinding model of talkback is not same as leanback,
causing unpreditive manner.  Disable it before we figure out how to
customize accessibility focus finder.

2. Fix guided action item's accessibility focus,  make TextView not
focusable before it's in editing and disable focusable after TextView
loses focus.
