  AX: Using aria-activedescendant to set the active cell within a grid does not convey focus movement
https://bugs.webkit.org/show_bug.cgi?id=231993
rdar://84439987

Reviewed by Tyler Wilcock and Andres Gonzalez.

To support the aria-activedescendant flow that is being described, we need to support AXSelectedCells for tables and grids.
This boils down to:
  1) Exposing and implementing AXSelectedCells as an attribute.
  2) Posting notifications when it changes.
  3) Implementing WKTR and DRT methods for fetching
  4) Changing the older, unused AXSelectedCell -> AXSelectedCells.
