USB: core: additional Device Classes to debug/usb/devices

Several newer USB Device classes are not presently reported individually at
/sys/kernel/debug/usb/devices, (reported as "unk."). This patch adds the
following classes: 0fh (Personal Healthcare devices), 10h (USB Type-C combined
Audio/Video devices) 11h (USB billboard), 12h (USB Type-C Bridge). As defined
at [https://www.usb.org/defined-class-codes]

Corresponding classes defined in include/linux/usb/ch9.h.
