security/intel/cbnt: Add option to generate BPM

This add an option to generate BPM using the 9elements bg-prov tool
using a json config file.

A template for the json config file can be obtained via
"bg-prov template".
Another option is to extract it from a working configuration:
"bg-prov read-config".

The option to just include a provided BPM binary is kept.
