Track metrics for core and std crates, add loop metrics (#258)

The crate that we compute metrics for is now configurable when invoking
`kani_std_analysis.py`. Should we find a need for further crates beyond
`core` or `std` we just need to invoke it more times.

We are now also reporting loop/no-loop information across all the kinds
of functions we are tracking as metrics.
