perf, x86, Pentium4: Add RAW events verification

Implements verification of

- Bits of ESCR EventMask field (meaningful bits in field are hardware
  predefined and others bits should be set to zero)

- INSTR_COMPLETED event (it is available on predefined cpu model only)

- Thread shared events (they should be guarded by "perf_event_paranoid"
  sysctl due to security reason). The side effect of this action is
  that PERF_COUNT_HW_BUS_CYCLES become a "paranoid" general event.
