Support accessibility in History.

Fixes: 33429660

Toggle accessibility importance of main Calculator elements based on
the open state of DragLayout. This is necessary due to the fact that
Talkback does not use visibility as a cue for determining accessibility
importance in RelativeLayout, which is the base class of DragLayout.
Without this workaround, it's possible to traverse to main Calculator
elements even when HistoryFragment is open.
