perf tools: Add evlist__disable_evsel/evlist__enable_evsel
Adding interface to enable/disable single event in the evlist based on
its name. It will be used later in new control enable/disable interface.
Keeping the evlist::enabled true when one or more events are enabled so
the toggle can work properly and toggle evlist to disabled state.
