feat!: always print Type::Constant kinds

[michaeljklein]

Description

Problem*

Instead of printing:

Expected type [RootParityInput; 4)], found type [RootParityInput; 4)]

We print:

Expected type [RootParityInput; (4: u32)], found type [RootParityInput; (4: Field)]

There are no changes in circuit sizes

We should almost never print constant kinds, this is the same formatting which broke #6077.

We need to either only print these when they differ or use a different error type entirely for this case. We should see what Rust does here.

[jfecher]

For:

struct Foo<const N: usize> {
    x: [u8; N],
}

fn main() {}

fn bar<const M: u32>() -> Foo<M> {
    todo!()
}

Rust gives:

error: the constant `M` is not of type `usize`
 --> t.rs:8:27
  |
8 | fn bar<const M: u32>() -> Foo<M> {
  |                           ^^^^^^ expected `usize`, found `u32`
  |
note: required by a bound in `Foo`
 --> t.rs:2:12
  |
2 | struct Foo<const N: usize> {
  |            ^^^^^^^^^^^^^^ required by this bound in `Foo`

The original issue appears to be resolved by #6083
