Allow to specify the file name for the proof

[LogvinovLeon]

Problem

Currently nargo always generates a proof in ${monorepoRoot}/proofs/${packageName}.proof.
This does not work for server side applications that generate multiple proofs in parallel as they can override each other.
nargo prove command already allows to specify Prover.toml & Verifier.toml names. Proof name should also be configurable

Happy Case

nargo prove --proof-path ../custom_proofs/uuid.proof

Project Impact

Blocker

Impact Context

Without it - each proof needs to be generated in a separate file system or all proofs need to be generated sequentially

Workaround

Yes

Workaround Description

Kinda. As described above

Proving functionality is being removed from nargo as part of #4960 to instead use bb directly which does support this.

[LogvinovLeon]

@TomAFrench is there any documentation on how to use bb directly to achieve that? As of now - nargo is still the recommended way of doing things even on dev version of nargo docs: https://noir-lang.org/docs/getting_started/hello_noir/
