Closes AztecProtocol/barretenberg#1312.

Removes the 4 byte metadata from proof and public inputs produced from the to_buffer</*include_size=*/true>() function. We are able to serialize and deserialize without this metadata by use many_from_buffer for deserialization.

The result is that we get to remove a lot of ugly if statements and weird proof parsing based on the metadata.

had to fix this as it wasn't exiting with the right exit code based on verified. It was just always exiting with 0, so tests would pass even if verified was false.

wow honk_recursion_2, would've never guessed without looking into the method body that it stands for ipa_accumulation, thanks for renaming!
