Fix GudiedStep GridView focus 2nd try

Setting focusable in style/layout doesn't work for RecylerView,
so set the attribute in GuidedActionsStyleList.

Making grid view not focusable causing another issue: in Fragmet
to Fragment transition, fragment.onResume() does not have any item
view in the action list yet.  So actionlist.requestFocus() gets
ignored.  Fixing this by declaring focusableViewAvailable() when
RecylerView layout pass added focusable children.
