chore: remove warnings from protocol circuits (#10556)

Remove all warnings in `noir-protocol-circuits`. Except for `poseidon2_hash_with_separator_slice`, which still calls private methods on Poseidon2. This will be removed by the blob pr because sponge blob also needs access to those. Also updated `array_to_bounded_vec` to be unconstrained and use `BoundedVec::from_parts_unchecked`.
