Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array of events, thus saving space for trace event probes. Protecting declarations with ifndef _TRACE_SAMPLE_DEF_ is required if we want to ensure that, e.g., structure forward declarations do not generate extra semicolons. It's already needed for enumerations and static inline functions declarations, but not documented, so document it here.
