If we're removing |code| string to native keycode, what about removing this as
well?

I had left them because the uses were outside tests, but sure. Also removed
UsbKeycodeToCode, which was not used externally.

On further inspection, it looks like all the users of this, and their five
defining files content/renderer/pepper/usb_key_code_conversion*.*, can be
removed entirely now that blink::WebKeyboardEvent contains the DOM |code|. Will
test and update.
