Enable function parameter idents in format strings

[vezenovm]

Problem

In this PR https://github.com/noir-lang/noir/pull/1952 format strings are being added to enable easy string interpolation for printing. During name resolution a string literal is checked for identifiers and compared in the most recent scope.

When converting these identifiers to expressions we check the definition info of each ident to fetch an expression. However, for function parameters an identifiers expression is not stored as its definition. This leads to this panic:

Message:  ICE: format string field requires expression
Location: crates/noirc_frontend/src/monomorphization/mod.rs:268

when attempting to do something like this:

fn print_in_func(x: Field, y: Field) {
    std::println(f"x: {x}, y: {y}");
}

This requires having to set function parameters to intermediate variables before printing them.

Happy Case

We should be able to print function parameters like any other identifier.
