[QS] Disallow TYPE_VIEW_SELECTED events
QS is announcing all of its items due to setSelected being called on the
TilePage.
Fixed by disable a11y on the page until setSelected is done. This will
cover all fringe cases of setSelected being passed along down the
hierarchy and additional a11y events being sent on child views.
Test: Manually verified that labels aren't announced
