Reset TLS 1.3 ciphers in SSL_CTX_set_ssl_version()

Historically SSL_CTX_set_ssl_version() has reset the cipher list
to the default.  Splitting TLS 1.3 ciphers to be tracked separately
caused a behavior change, in that TLS 1.3 cipher configuration was
preserved across calls to SSL_CTX_set_ssl_version().  To restore commensurate
behavior with the historical behavior, set the ciphersuites to the default as
well as setting the cipher list to the default.

Closes: #7226
