ALSA: usb-audio: UAC3 Add support for connector insertion.
This adds support for the UAC3 insertion controls. The status is reported as a boolean value in the same way it used to do for UAC2. Hence, the presence of any connector in the response will make the control saying the jack is connected. The UAC2 support for this control has been moved to a dedicated control for connectors as both UAC2 and UAC3 follow a specific Control Request Parameter Block for this control. This parameter block for UAC3 could not be read in the same simplistic manner as in UAC2. This implementation is not requesting additional information from the HIGH CAPABILITY Connectors descriptor. Tested with an UAC3 device with UAC2 as legacy configuration. The connector status can be read with `amixer` and the interrupt is also caught with `alsactl monitor`.
