tracing: Move find_event_field() into trace_events.c

By moving find_event_field() and trace_find_field() into trace_events.c,
the ftrace_common_fields list and trace_get_fields() can become local to
the trace_events.c file.

find_event_field() is renamed to trace_find_event_field() to conform to
the tracing global function names.
