usb: core: Add support to handle multi config audio device

A USB audio class 3.0 based device may express different audio interface
associations representing the same underlying hardware by using multiple
USB device configuration descriptors. Using BOS configuration summary
descriptor host software can choose which configuration to set. This is
done by going over list of configuration summary descriptors and selecting
the first available configuration supporting BADD subclass of UAC 3.0
protocol.
