Add API Docs parser to the repository

[ovflowd]

This issue concerns adding the existing API docs parser from the nodejs.dev repository to this repository.

The original files described on the source repository are:

• https://github.com/nodejs/nodejs.dev/blob/main/util-node/apiDocsTransformUtils.js
• https://github.com/nodejs/nodejs.dev/blob/main/util-node/apiDocsTypeParser.js
• https://github.com/nodejs/nodejs.dev/blob/main/scripts/syncApiDocs.js
• https://github.com/nodejs/nodejs.dev/blob/main/util-node/getApiDocsData.js

The files above will be repurposed, changed, and updated to achieve the initial goal of:

• Having a constants.mjs file with all sorts of constants
• Extracting certain utils into separate files
• Extracting Regular Expressions to a queries.mjs
• The main logic will be extracted for now to a parser.mjs file

The initial API aim is to provide a function where the input is the VFile of an API doc, and the output is its transformed contents into MDX as a string.

This will also require a package.json and possibly a few packages to be added to the project.

I'm finally working on this :)
