HID: hid-debug: more informative output for EV_KEY
Currently hid-debug's hid_resolv_event prints questions marks for all entries without explicit mapping information. This makes debugging unnecessarily complicated as multiple different keys may simply result in the same uninformative output. Some common event codes are deliberately not defined in input-event-codes.h. For example the 16th gamepad key. Instead, print the hexadecimal codes for all events without symbolic names.
