perf tools: Introduce opt_event_config nonterminal
To remove duplicated code that differs only in using the matching
'/a,b,c/' part or NULL if no event configuration is done ('//' or no
pair of slashes at all).
Will be used by some new targets allowing the configuration of hardware
events, etc.
Lifted part of the 'opt_event_config' nonterminal from a patch by Wang
Nan.
