This PR makes all macros in the test_utils module public to allow for easier testing of hints (and other features) living in other crates/repositories.

Fixes #1595.

This is not really vm-related, so I don't think it should be included in the vm's public api. Moreover, we may choose to remove the usage of BigInt from the VM altogether and remove this macro too.

Makes sense. I made it public out of simplicity because keeping it pub(crate) in a now public module induces a few unused import warnings. I'll find a solution.

This is an auxiliary macro used to implement the memory macro, it shouldn't be made public

These macros need to be public to make the memory and segments macros usable. Users need to import them as well.

Only solution I found for this is to split the import in two and

    #[allow(unused_imports)]
    pub(crate) use crate::stdlib::collections::BTreeMap;
    pub(crate) use crate::stdlib::sync::Arc;

Tell me if you have a better solution.

Program is already public, we should use the full path in the macro rather than re-exporting it here

This PR should be mergeable. Most of the macros need to be public as they are used in public macros. I addressed all the comments that could be.

Why did you made these 2 fields public? they are private to make it easier to refactor the representation and improve it. There are many methods for retrieving and inspecting the Memory and pretty-printing it (Display instance).

Same, some macros access these fields directly so they must be public to use the macros out of tree. I'll try to think of another solution.

Some of the macros in test_utils require access to this field. As the goal is to make the macros usable out of tree, the easy solution is to make this field public. I understand the concern though. Any suggestion on how to work around the issue?

It depends on what you want to do in the tests. Maybe you could just use the insert family of functions.

Hello! Making these macros public in the current state involves making a lot of fields internal to the VM public which is not desirable at all. I think we should address this task in a different way. What these macros currently do can be implemented using the vm's public api, so we should re-implement or implement new macros that use the public api instead.
