Update JSON/events for power10 platform with additional events.
Also move PM_VECTOR_LD_CMPL event from others.json to
frontend.json file.

Thanks, applied to tmp.perf-tools-next,
This seems to be causing this:

This happened in the past, I'm now trying to figure this out :-\

This was in:

toolsbuilder@five:~$ cat dm.log/ubuntu:18.04-x-powerpc


So 32-bit powerpc, ubuntu 18.04
This did the trick, so I fixed it in my repo, please ack, just replacing
’ with ' :-\

Hi Arnaldo,
  Thanks for fixing it. I will make sure in next series of patches, we
are also checking for this combination to avoid ascii issue.

Change looks fine to me.

Thanks,
