scripts/lib/bsp/engine.py: add handling for JSON strings

Normally pre-canned properties are supplied as JSON from a file, which
the user can specify using e.g. the -i option.

We can reuse that basic functionality for dedicated command-line
parameters by sythesizing a JSON string containing those param values
on the fly and passing that in instead.

This adds the ability for the common creation code to accept JSON
strings as well as JSON files.
