QUIC: using native TLSv1.3 cipher suite constants. After BoringSSL aligned[1] with OpenSSL on TLS1_3_CK_* macros, and LibreSSL uses OpenSSL naming, our own variants can be dropped now. Compatibility is preserved with libraries that lack these macros. Additionally, transition to SSL_CIPHER_get_id() fixes build error with LibreSSL that doesn't implement SSL_CIPHER_get_protocol_id().
