deps: add acorn stage-3 plugins
This adds bigint, class-fields, numeric-separators, static-class features, private class methods and fields as dependency. That way it's possible to use these in combination with acorn to parse these language features. This also removes a couple of files that were not necessary for Node.js to reduce the code base.

# BigInt support for Acorn
2+
3+
[![NPM version](https://img.shields.io/npm/v/acorn-bigint.svg)](https://www.npmjs.org/package/acorn-bigint)
4+
5+
This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.
6+
7+
It implements support for arbitrary precision integers as defined in the stage 3 proposal [BigInt: Arbitrary precision integers in JavaScript](https://github.com/tc39/proposal-bigint). The emitted AST follows [an ESTree proposal](https://github.com/estree/estree/blob/132be9b9ec376adbc082dd5f6ba78aefd7a1a864/experimental/bigint.md).
8+
9+
## Usage
10+
11+
This module provides a plugin that can be used to extend the Acorn `Parser` class:
12+
13+
```javascript
14+
const {Parser} = require('acorn');
15+
const bigInt = require('acorn-bigint');
16+
Parser.extend(bigInt).parse('100n');
17+
```
18+
19+
## License
20+
21+
This plugin is released under an [MIT License](./LICENSE).
