Use EditorConfig as for autoformat

[toastal]

I would like to see EditorConfig be used as a fallback for the default spacing when no format values are specified.

Advantages: keep indentation config in one place; no desync in config/execution; no need to pass arguments or override; ability to specify different values for different files/directories if needed for vendored third-party files; autoformat would use it by default

Disadvantages: requires parsing .editorconfig, a third-party format & would incur additional dependencies; minor endorsement of EditorConfig as a project since it would get special support

I think I would consider editorconfig support in the main API itself to be out of scope. We don’t even deal with files!

Where I do think it makes sense is as part of a standalone kdlfmt tool, which would be good to have in general
