servodtool: add device usb-comms
This new helper is designed to identify USB communication failures on
devices that are seemingly present on the system e.g. devices that
enumerated successfully, but have since then lost their data lines for
example, or where leakage current continues to present them as a valid
device when the connection has in actuality been cut off.
BUG=b:183250135
// servo v4 + ccd on grunt, all device working
TEST=sudo servoodtool device -s 0403C044-92D9C359 usb-comms && echo $?

sudo servoodtool device -s C1706310714 usb-comms && echo $?

// servo v4 + ccd on grunt, ccd signal artifically broken (no SBU
// forwarding from grunt)
// shows that tool can identify ccd is broken but v4 remains operational
