[tools] refactor: update/hash checking scripts, use tags for more deps

Uses tags for a bunch of deps that can use them

Also adds a bunmch of scripts to tools/cpm, notably for checking hashes
and checking for updates.

TODO:
- Documentation
- CI target to check hashes
- Script to update the json directly (dedup)
- Function to filter tags (dedup)
- Weekly CI to check for updates

Need to get that other CI runner up
