Replace c_binds with c_bind_new in barretenberg

[kevaundray]

Problem

We currently have duplicated code related to c_bind and c_bind_new. Ideally we remove the c_bind files and only use c_bind_new.

The issue right now is that circuits relies on c_bind, and so we cannot remove it right now. Noir's acvm_backend_wasm also uses c_bind.

Solution

Either we have circuits and Noir calling the methods in c_bind_new and or we have those components re-implement the necessary logic.
