tracing/selftest: Add selftests to test trace_marker histogram triggers

Browse source

Add a couple of tests that test the trace_marker histogram triggers.
One does a straight histogram test, the other will create a synthetic event
and test the latency between two different writes (using filters to
differentiate between them).
