perf tools: Adds the tracepoint name parsing support

Browse source 
Adds rules for parsing tracepoint names. Change rules of tracepoint which
derives from PE_NAMEs into tracepoint names directly, so adding more rules
based on tracepoint names will be easier.

Changes v2-v3:
   - Change __event_legacy_tracepoint label in bison file to tracepoint_name
   - Fix formats error.
