Move usb_keycode_map.h into ui/base/keycodes.

This file contains the mapping table to convert to/from USB scan codes and
native Mac, Win and Linux key codes.

Currently, 2 exact copies of this file exist:
 * webkit/plugins/ppapi
 * remoting/host
This cl combines these files into one super-powerful USB key mapping table!
