rGb93f6bfca343: hid: Port ukbd to HID and attach to build

Summary

This imports hkbd(4) driver which is conversion of existing ukbd(4) to the HID subsystem.

Unlike ukbd which is running entirely under Giant, hkbd uses 2 locks - private mutex for interrupt handler/repeat callout and Giant for syscons interface. Lockless queue is used for passing of key-press events from mtx-protected code to Giant-protected one. Other differences are minor.
