tools lib traceevent: Factor out and export print_event_field[s]()

The print_event_field() and print_event_fields() functions print basic
information of a given field or event without the print format.  They'll
be used by dynamic sort keys later.

Committer note:

Rename it to pevent_print_field[s]() to get proper namespacing, as
discussed with Steven Rostedt.
