feat(parser): implement GritQL parsing

[arendjr]

Summary

Based on the open-source GritQL grammar, this PR implements a parser for GritQL in Biome.

I'll admit I had underestimated how much manual parsing logic needed to be implemented, but I've gotten the hang of it and progress is moving fast now.

It's nice that the codegen also seems to generate most of the formatter already, but I have to take a closer look still to see it really works.

TODO:

• Implement maps and lists
• Implement assignments
• Implement definitions
• Refine error resilience? Maybe @ematipico or @Conaclos can have a look if I'm doing it the right way
• More test cases
• Finish up formatter

Test Plan

Still adding test cases.

I need to ask you to break down this PR in smaller PRs. It's impossible to review it. Sorry about that.

Some advice on how to break it down:

1. start with a PR of the grammar and its code generation;
2. then a PR that contains the parsing only;
3. the formatter is not needed, the code-generation of the formatter is done a different step, which can be ignored. If you wish to add it, it can be done in a separate PR

No worries! I think I'll first get the parser complete, since at least initially I sometimes needed to tweak the grammar based on what I discovered implemented the parser. It's probably mostly stable by now, but if you don't mind I'll just use this one to track my progress, and then split things to get it reviewed and merged.

[arendjr]

I created test cases out of most of the snippets in the Grit docs and they all parse. Still have some FIXMEs in there and I think I might have some precedence issues still, but next step will be splitting this PR :)
