thunderbolt: Move control channel messages to tb_msgs.h
We will be forwarding notifications received from the control channel to the connection manager implementations. This way they can decide what to do if anything when a notification is received. To be able to use control channel messages from other files, move them to tb_msgs.h. No functional changes intended.
