perf tools: Split event symbols arrays to hw and sw parts
It'll be convenient in upcoming patch to access hw event symbols strings via enum perf_hw_id indexes. In order not to duplicate the data, creating two separate arrays: event_symbols_hw for enum perf_hw_id events event_symbols_sw for enum perf_sw_ids events Changing the current event list code to follow the change.
