simpleperf: list cmd: Check raw event support on each cpu model

The list cmd reports a raw event is supported when we can get a
non-zero counter value for that event. But this isn't accurate.
Because a raw event may only be supported on part of cpus on the
device.

To fix this, check and report raw event support on each cpu model
on the device.

Output before the CL:
raw-br-immed-retired (may not supported)
  # Instruction architecturally executed, immediate branch

Output after the CL:
raw-br-immed-retired (supported on cpu 0-7, may supported on cpu 8)
  # Branch Instruction architecturally executed, immediate
