EntryFilesAnalyser: detect recursion

[fraxken]

Detect recursion between files during the analysis

At the end we should be able to retrieve edges between files (with corresponding node location I guess)

example:

First file is bar.js (entry file)

import { foo } from "foo.js";
console.log(foo);

export const bar = 5;

Then foo.js

import { bar } from "bar.js";
console.log(bar);

export const foo = 10;
