I wonder how long will it take to use this macro in the upstream OpenSSL.
Given that QuicTLS may be considered as something interim,
I think it should be ok for now.
And it respects the no-quic QuicTLS build option.
Together with the adjusted log summary:
QUIC: using SSL_set_quic_early_data_enabled() only with QuicTLS.
This function is present in QuicTLS only. After SSL_READ_EARLY_DATA_SUCCESS
became visible in LibreSSL together with experimental QUIC API, this required
to revise the conditional compilation test to use more narrow macros.
