perf script perl: Removing event cache as it's no longer needed
perf script perl: Removing event cache as it's no longer needed

We don't need to maintain cache of 'struct event_format' objects.
Currently the 'struct perf_evsel' holds this reference already.

Adding events_defined bitmap to keep track of defined events, which is
much cheaper than array of pointers.
