feat: Add "after-all" hook for testing

[lucas-manuel]

Component

Forge

Describe the feature you would like

In forge testing it would be very helpful to have a hook that runs at the end of each test. This would allow for:

• Single logging of metrics as outlined in this issue as an intermediate measure until native internal metrics are implemented.
• Post fuzz campaign testing (e.g., close out all positions and assert all funds are able to exit the system) (both fuzzing and invariant testing).

Additional context

No response

Just noting that contrary to the issue name, this does not have to be exclusive to invariant tests, and can apply to all tests. However in that case some use cases such as logging don't apply. So we may need multiple functions like afterInvariant, afterFuzz, and afterConcrete. But that feels a but cluttered, so maybe there's a single afterAll(TestType) with overloads. Needs some though here

Up to you but I wouldn't mind a one size fits all personally
