feat: Make `IntoCircuitInputValue` trait and associated utils (`into_u96_guarantee`) public in `circuit.cairo`

[feltroidprime]

Cannot implement the trait for other types than u384 when using edition 2024

The goal is to implement this trait for other structs, and have generic function like

pub fn run_circuit<T, +IntoCircuitInputValue<T>, +Drop<T>>(value: T) -> (u384,) 

But the trait needs to be imported, both to implement it (into_u96_guarantee is useful as well to export if not mandatory) and to run functions

Example here :

Can I be assigned to this?

why do you need this exactly? what is the exact optimization you are planning?
because for your specific plan - you can just ask for an Into<T, u384>.
