Add a prelude module in the noir_stdlib

[jfecher]

Problem

Features like dep::std::println and the upcoming assert_eq are commonly used, core features and can be annoying to have to import into most files.

Happy Case

These symbols are automatically imported into each file, along with any other symbols in a new prelude.nr file in the stdlib.

I think they're useful 🤷. Something being a builtin keyword or being imported automatically is more of an implementation detail than anything.

I would like to experiment with a completely different import system rather than the one most languages use in which developers just pray for tools to automate it for them. Although that is a different topic and likely not for Noir with it's strong Rust influence.

For features preluded, is there a common practice in Rust / other languages on whether if they should be kept:

• Within the stdlib codebase
• Within the Standard Library doc section
  ?

Thinking if it would be unnecessarily noisy for users if yes.
