Implement support for selectors DSL in Oxlint JS plugins. The implementation is based on ESLint's implementation. Like ESLint, it uses [esquery](https://www.npmjs.com/package/esquery) as the underlying selector parser and matcher. One detail is not implemented. ESLint ensures that visit functions are called in order of their "specificity" with the most specific called first. This implementation just calls them in the order they're defined. This is a shortcoming and will need to be fixed in future, but I imagine that in practice visitation order makes no difference for the vast majority of rules. I've made what I hope are some optimizations versus ESLint's version. Notably: 1. Making simple selectors which unconditionally visit a subset of nodes (e.g. `:matches(FunctionDeclaration, FunctionExpression)` bypass the selector match process - as it'd always return `true` anyway. 2. Faster implementations of union and intersection.
