Subject: [PATCH] Return wxACC_NOT_IMPLEMENTED from
 wxWindowAccessible::GetParent()

If a widget has a custom accessibility implementation derived from
wxWindowAccessible, there's no guarantee that the parent overrides the
nullptr-returning base CreateAccessible.

Returning wxACC_NOT_IMPLEMENTED follows the pattern of other
accessibility methods to defer to the platform's default implementation,
and fixes wx wxWindowAccessible::GetParent() when called on custom
accessibility implementations like wxCheckListBoxAccessible.

Closes #26063.
