libtracefs: Add define for ALL dynamic events
Some of the tracefs APIs for dynamic events accept bitmask of events. If
a caller wants to address all types of events, it should list them in
the bitmask. This logic is fragile. When a new type of dynamic event is
introduced, the API callers should be modified. That's why a new define
is added, part of the library API, to address all types of dynamic
events.
