Description

Use the field attribute to restrict some functions in stdlib to bn254 field

Problem*

Some stdlib functions require that noir native field is the one from bn254 curve, so we use the new field attribute so that these functions cannot be used if the field is different.

Summary*

Add the attribute #[field(bn254)] to a few functions in stdlib, such as:
poseidon, babyjubjub and mimc.

I'm fine with merging this right now, but it does feel that the attributes in noir_stdlib/src/hash/poseidon/bn254/perm.nr are unneeded as they should be encapsulated by the bn254 module instead.

But we do not have attribute for modules?

Yeah we do not, but each method calls permute from the bn254 module which has the attribute on it. It would be nice to be able to specify on the module itself as well, but I think this is good for now.

Yeah it would need to be introduced in a separate PR
