Reorganize run_cipher_per_proto()
This PR reorganizes run_cipher_per_proto(). Currently run_cipher_per_proto() runs a for loop, which loops over each protocol and prints the set of supported ciphers for each protocol. This PR simply places the body of the for loop in a separate function from the loop itself. This allows the body of the loop to be called for just a single protocol. While this PR does not change the way that testssl.sh functions, it would allow for a future change in which run_server_preferences() called cipher_pref_check() for protocols in which the server enforces a cipher order and calls ciphers_by_strength() for protocols in which the server does not enforce a cipher order.
