Documentation/trace/tracepoints.txt: add links to TRACE_EVENT documentation

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

Existing tracepoint documentation doesn't mention the popular
TRACE_EVENT macro. Since an excellent series of articles on proper
usage already exists, respective links are added to the existing
documentation.
