Fix false positive with cast_sign_loss lint
...
`cast_sign_loss` lint incorrectly suggests that the result of
`checked_abs`, `rem_euclid` and `checked_rem_euclid` cannot
be casted to an unsigned integer without loss.

Fix cast_sign_loss false positive
...
This checks if the value is a non-negative constant before linting about
losing the sign.
Because the `constant` function doesn't handle const functions, we check if
the value is from a call to a `max_value` function directly. A utility method
called `get_def_path` was added to make checking for the function paths
easier.
