list supported groups and curves

[Wall, Stephen]

Is there a way to list the supported curves and groups with openssl?  I saw nothing in the `openssl list` command.  I’m interested mainly listing all the valid values for SSL_CTX_set1_group_list().  I see the man page for that function has a list of valid groups/curves for TLS 1.3, but also mentions providers can change that list, and does not give a list for valid curves in other TLS versions.
