perf evsel: Provide a new constructor for tracepoints
The existing constructor receives a perf_event_attr filled with the
event type and the config.
To reduce the boilerplate for tracepoints, provide a new constructor,
perf_evsel__newtp() that receives the tracepoint name and will open
the debugfs file, call into libtraceevent new pevent_parse_format file
to fill its ->tp_format member, so that users can then just call
perf_evsel__field() to access its fields.
