This patch does several things: 1. Remove virtual cursor doc accessible member. 2. Remove state-keeping nsAccessiblePivot implementation and replace it with something that is much more similar to the native Pivot interface. 3. Move nsIAccessiblePivot implementation to xpcom and rename it xpcAccessiblePivot. 4. Delete mochitests and introduce browser tests. 5. Make new xpcom implementation work on remote accessibles as well. Differential Revision: https://phabricator.services.mozilla.com/D181813
