New oxlint-config package

[AleksanderEvensen]

Motivation:

Recently been using the oxc lint and formatting toolchains on my projects. They are close to supporting most common eslint plugins natively with support for the majority of the eslint js API. I wanted to add oxlint and oxfmt as tooling option in the @tanstack/cli builder tool, and since the eslint option used the tanstack/config eslint package I thought that starting here would be a good stepping stone before adding it as an option in the builder CLI

Rules requiring extra TypeScript-native package

TypeScript native (tsgo) is not released yet, so decided to not include these rules as they also require the user to add an extra oxlint-tsgolint

• @typescript-eslint/no-for-in-array
• @typescript-eslint/no-unnecessary-type-assertion
• @typescript-eslint/require-await

🎯 Changes

Adds a new oxlint-config package that can be used just like the eslint-config package.

It's almost a one-to-one copy of the @tanstack/eslint-config package with some rules omitted due to missing implementations.

Usage:

// oxlint.config.ts
import { defineConfig } from 'oxlint'
import { tanstackConfig } from '@tanstack/oxlint-config'

export default defineConfig({
  extends: [tanstackConfig],
})

As far as i know does not support the .oxlintrc.json format.
