Instead of passing an XAccessibleContext wrapped in a uno::Any, pass the XAccessible. This drops an extra level of wrapping/unwrapping. The same will be done for XAccessibleGroupPosition::getObjectLink in an upcoming commit. Since the XAccessibleGroupPosition interface (and the UNO a11y API in general) is unpublished and meant for internal use only, changing it should be unproblematic.
