Queue of backend breaking changes

[kevaundray]

Problem

This issue list a batch of breaking changes to backends that we want to ideally merge around the same time:

• We have renamed NpLanguage to ExpressionWidth and removed the partial backend feature.

We need to remove the opcode supported fields in backends and rename language to expression_width in the info.json file

• We have removed hash_to_field

We need to remove this from ACIR and regenerate the serialization

• We want to add blake3 opcode

We need to add the opcode into ACIR and regenerate the serialization

Happy Case
