refactor: reduce calls of find_pending_xref_conditions (refs: #9240)

After #9246, `find_pending_xref_conditions()` should be only called from
intended modules.  At present, the Python Domain is the only module to
call it intendedly.  Therefore, this removes the needless calls of the
utility function from "unintended" modules.
