Feature: exception sorting as makefile targets

[Itaykal]

What this PR does / why we need it?

This PR adds two Makefile targets, one for validating the exception files' sorting, and the other to sort them recursively.
I took the code added in #295 and converted it to targets, thus simplifying both the Github action and the developer's workflow.
