Add recursion opcode into format

[kevaundray]

Problem

Once [https://github.com/noir-lang/acvm/issues/198] is resolved, we will need to add a way to serialize this new opcode to barretenberg.

This is blocked by barretenberg actually knowing how to do recursion

Proposed solution

Add serialization of recursion type into the backend.
