common/utrace: Add CS logging support
Viewing CS traces retrieved from the driver is common practice to
determine driver bugs but there is no way to determine what
function a certain part of the CS was emitted by. This is crucial
information to determine what function is responsible for emitting
broken CS packets and to help with navigation of the CS trace.
