Commit license-metadata.json to git and check it's correct in CI

[jonathanpallant]

This PR adds license-metadata.json to the root of the git repo, and changes mingw-check to check that the file is still up-to-date.

By committing this file, we remove the need for developers to a) have reuse installed or b) run an expensive ~90 second analysis of the files on disk when they want generate the COPYRIGHT.html files which depend on this license metadata.

The file will need updating whenever REUSE.toml changes, or when git submodules are added, or when git submodules change their license information (as detected by REUSE).

You can now run:

• ./x run collect-license-metadata to update the ./license-metadata.json file
• ./x test collect-license-metadata to test the ./license-metadata.json file for correctness

The comparison is done with two serde_json::Value objects, so the map objects they contain should ignore differences in ordering.

Thank you, this was a pleasure to review. It's almost as if you're not doing this for the first time :laughing:
