SslContextBuilder handles null (meaning "uses default cipher suites/protocols"), so we can omit null checks in all users of these new configs.

Add protocol and cipher config to gRPC TLS config
Please describe your PR in detail:
This change enables Ozone administrators to restrict TLS protocol versions and cipher suites on all gRPC server endpoints (OzoneManager, XceiverServer, ReplicationServer, InterSCMGrpcProtocolService) via two new configuration keys: hdds.grpc.tls.protocols (e.g. "TLSv1.3") and hdds.grpc.tls.ciphers
(e.g. "TLS_AES_256_GCM_SHA384,TLS_AES_128_GCM_SHA256").
When unset, provider defaults are preserved for full backward compatibility. The configuration is parsed in SecurityConfig and applied server-side only — clients are intentionally unrestricted since the server controls TLS handshake negotiation.

What is the link to the Apache JIRA
https://issues.apache.org/jira/browse/HDDS-15094
How was this patch tested?
New tests verify both config parsing (7 cases in TestSecurityConfigTlsSettings) and actual TLS handshake enforcement including protocol version rejection and cipher mismatch failure (5 cases in TestGrpcTlsConfig).
