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
+
+[![NPM version](https://img.shields.io/npm/v/acorn-bigint.svg)](https://www.npmjs.org/package/acorn-bigint)
+
+This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.
+
+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).
+
+## Usage
+
+This module provides a plugin that can be used to extend the Acorn `Parser` class:
+
+```javascript
+const {Parser} = require('acorn');
+const bigInt = require('acorn-bigint');
+Parser.extend(bigInt).parse('100n');
+```
+
