Ignore some HomeKit devices (#15316)

There are some devices that speak HomeKit that we shouldn't expose. Some
bridges (such as the Hue) provide reduced functionality over HomeKit and
have a functional native API, so should be ignored. We also shouldn't
offer to configure the built-in Home Assistant HomeKit bridge.
