Implement ArrayBuffer built-in object

[Razican]

ECMASCript feature
The ArrayBuffer object is used to represent a generic, fixed-length raw binary data buffer. You can check how this works in the MDN, and in the specification.

Example code

const buffer = new ArrayBuffer(8);

Tips for implementation
You can see #1033 to get ideas on how to implement the ArrayBuffer object. Feel free to ask for mentoring.

Hi @Razican . I'm willing to begin contributing to Boa regularly.
Would you give me a hand on a first issue?

Feel free to assign any good first issue to me, i'll take it

Would you like to take this one? It's not marked as "good first issue", but I think it's a good one to learn about built-in objects. Let me know if you'd like any help :)

Sounds good. I'll take this one
