refactor(auth_registry): move contract to contracts/canonical/

Now that auth_registry is no longer a magic-address protocol contract,
`contracts/protocol/` was misleading. Establishes a `canonical/` sibling
directory for non-protocol contracts deployed at well-known
artifact-derived addresses (deployed in early blocks, not at genesis,
not part of protocolContractsHash). Paths updated in noir-contracts'
top-level Nargo.toml, avm_test_contract's dep, the cycle guard script,
and derive_auth_registry's AUTH_REGISTRY_SRC_DIR.
