generate_ha: a command GA the actuator reports on is its own state address

Found on a real 1312-GA house (43 of 159 "switch without status" had a Read+Transmit
object on the command GA), measured on all seven corpus projects.

detect_missing_status already counted these as satisfied through pairing.self_reporting();
the generator did not and put them on the review list without a state_address. It now
uses the same function: no separate status found and the command GA has an R+T object
-> state_address = the command GA. Same for the on/off sibling of a dimmable light and
for brightness_state_address on a self-reporting brightness GA. Write-only objects still
go to review.

Corpus: no entity count changed, no address lost; review items 598 -> 555 on the house,
-36, -40, -12, -1, -32 on the others. Test C in test_real_house_fixes.py covers R+T,
write-only and a non-lighting switch.

Not verified on a live Home Assistant: state_address equal to address is accepted by the
KNX schema and xknx reads from it, but no running instance was used here.
