tls: fix negative sessionTimeout handling #53002

For historical reasons, the second argument of SSL_CTX_set_timeout is a signed integer, and Node.js has so far passed arbitrary (signed) int32_t values. However, new versions of OpenSSL have changed the handling of negative values inside SSL_CTX_set_timeout, and we should shield users of Node.js from both the old and the new behavior. Hence, reject any negative values by throwing an error from within createSecureContext.
