perf tools: Remove event types framework completely

Browse source 
Removing event types framework completely. The only remainder (apart
from few comments) is following enum:

  enum perf_user_event_type {
    ...
    PERF_RECORD_HEADER_EVENT_TYPE           = 65, /* deprecated */
    ...
  }

It's kept as deprecated, resulting in error when processed in
perf_session__process_user_event function.
