doc, script: process perf-captured trace

Describe how to process trace captured with the Linux perf tool.

Add scripts to
  - extract the sideband streams
  - copy referenced files
  - compute --pevent options for ptdump and ptxed

from a file.

The perf-read-image.bash script it is no longer needed.  Remove it.
