fix: check values.contains_key before get_type_info

[Bashmunta]

Summary

Moved the values.contains_key() check before get_type_info() call to avoid redundant lookups, matching the pattern used in parse_circuit_inputs.

Why is this change needed?

In get_circuit_info, context.get_type_info() was called before checking if the value was already processed. Since the same gate can appear multiple times in the stack (shared inputs), this caused unnecessary lookups when the value already existed in values.

crates/cairo-lang-sierra/src/extensions/modules/circuit.rs line 1069 at r1 (raw file):

        if values.contains_key(&ty) {
            // The value was already processed.

why remove the doc?
