doc: Document that unloading in-process Active Qt may cause crash
Statically allocated Qt resources created by an Active Qt COM server may
become corrupted after unloading the COM server dll, if Qt modules other
than those found in QtBase are used. This change adds a DOC warning
about this problem and suggests a workaround.
Fixes: QTBUG-56172
