feat: Massive Refactor and Rewrite

[tamasfe]

One of the reasons why I always kept postponing patches and updates in this project was the fact that it was pretty hard to maintain. When I originally wrote most of it, I barely had time and just wanted to get features out ASAP.

The Even Better TOML has recently passed the 100K installs mark, I felt that some cleanup and care was long overdue.

This PR is pretty much a rewrite and/or a major refactor of Taplo with the only exception of the parser, which I would love to rewrite as well but I'm already pushing my time-limits.

Features

• Rewrite of the DOM, it now uses a reference-counted implementation where each node is cheap to clone and to juggle around.
• Rewrite of the CLI as well, it is now a first-class citizen not just something quickly thrown together.
• Integration of jsonschema, most (all?) JSON Schema features are now supported and the limitations of the current implementation are non-existent.
• Support of schema store catalog and schemas
• The shared code between the CLI and the language server is now properly extracted into taplo-common, so the CLI and the LSP are no longer out of sync.
• The external environment is now abstracted away into a trait, so both the LSP and the CLI should run pretty much anywhere with minimal plumbing
• tracing is used for all logging
• Refactor and workspace support in the LSP
• All toml-test tests now pass
• Proper benchmarks via criterion (the new DOM is slightly slower initially due to allocations, but not too much)
• Completions and hover in the LSP (the building blocks are there, but the cursor queries require some plumbing)
• The LSP is part of the CLI as well, and the VSCode extension works with it, WASM bindings are yet to be reimplemented
• Flexible configuration options in the LSP
• Proper directives in TOML files (e.g. schema)

Breaking Changes

Probably a lot, but here are a few notable ones:

• The DOM API is completely different, although migration should be rather easy.
• Chrono feature has been removed, it can be reintroduced later though if needed.
• As with the DOM layout, error types have also changed.
• Date types are now separate syntax-kinds.
• Even though we had no MSRV policy, I clearly used 1.58 features during the rewrite
• The Even Better Toml vscode extension also gets a facelift with some configuration options changed
