Commit Message: This commit fixes the lifetime issue of Http/TcpAccessLogConfig owned by HttpGrpcAccessLog and TcpGrpcAccessLog loggers. These logger objects may have died before the thread local callback for initializing thread local access loggers is actually executed in each thread. In the previous implementation, the callback only captures the reference to the AccessLogConfig object owned by HttpGrpcAccessLog/TcpGrpcAccessLog which might not outlive, and therefore potentially this causes the invalid memory access and crashes the Envoy in any thread. This happens especially when an xDS resource is NACKed.
