a11y: Redo cell accessible action handling

Multiple changes:
- actions are now available unconditionally, but only work in the right
  state. This mirrors other actions.
- instead of adding actions manually, they invoke the action on the
  GtkCellAccessibleParent interface.

Tests have been updated to reflect the changes
