perf tools: De-opt the parse_events function

Moving out the option parameter from parse_events function,
and adding new parse_events_option function instead.

The option parameter is used only to carry "struct perf_evlist"
pointer for chaining new events. Putting it away, enable us
to call parse_events from other places without using the
option parameter.
