feat(format/grit): grit formatter initial configuration

[branberry]

Summary

Create basic scaffolding/configuration for the GritQL formatter crate. I am realizing now that I probably started in the reverse order for the GritQL work, I probably should have started with the parser in hindsight.

With that said, this gets the bulk of the setup with the formatter out of the way, minus some tests. Will work to add that next.
