l2tp: add tracepoint definitions in trace.h
l2tp can provide a better debug experience using tracepoints rather than
printk-style logging.
Add tracepoint definitions in trace.h for use in the l2tp subsystem
code.
Add preprocessor definitions for the length of session and tunnel names
in l2tp_core.h so we can reuse these in trace.h.
