Disable remote proxy patching except AWS Lambda (#17415) To avoid unintended tampering with remote downstreams via service config, refactor BasicEnvoyExtender and RuntimeConfig to disallow typical Envoy extensions from being applied to non-local proxies. Continue to allow this behavior for AWS Lambda and the read-only Validate builtin extensions. Addresses CVE-2023-2816.

```release-note:security
extensions: Disable remote downstream proxy patching by Envoy Extensions other than AWS Lambda. Previously, an operator with service:write ACL permissions for an upstream service could modify Envoy proxy config for downstream services without equivalent permissions for those services. This issue only impacts the Lua extension. [[CVE-2023-2816](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-2816)]
```
```release-note:breaking-change
extensions: The Lua extension now targets local proxy listeners for the configured service's upstreams, rather than remote downstream listeners for the configured service, when ListenerType is set to outbound in extension configuration. See [CVE-2023-2816](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-2816) changelog entry for more details.
