Returns whether information about the OpenSSL environment should be dumped when first starting the
application, including supported ciphers.

<p>This flag is disabled by default. Specify the {@code -Dcom.linecorp.armeria.dumpOpenSslInfo=true} JVM
option to enable it.

<p>If {@link #tlsEngineType()} does not return {@link TlsEngineType#OPENSSL}, this also returns
{@code false} no matter what the specified JVM option is.
