Fixing the announcement of menu of a11y actions when using Talkback
or Switch Access. Root cause: The accessibility delegate was used for the root view instead of items. Actions: 1) Add the accessibility delegate to the individual items of the RecyclerView, and then override the functions onInitializeAccessibilityNodeInfo() and performAccessibilityAction(). 2) Remove the overridden functions onInitializeAccessibilityNodeInfo() and performAccessibilityAction() from the root view. Bug: 190326499 Bug: 190138534 Test: manual test Change-Id: Ife1787c2d7bb3090e4d55aed76c303e9842a1a98
