infra: update introspector and add new light version (#12983)

Adds a light version of FI that should work on all projects. This will
only be used if the existing FI does not work, e.g. due to failures
around LTO.

Also starts using the CLI version of fuzz-introspector as opposed to
calling `main.py`.
