Move the cipher content mapping into its own function (#7952)

save_cipher_data copies the request's type data or blob, name, notes, fields,
password history, key and reprompt onto the cipher through set_cipher_content
now, so code that stores a cipher without going through a request can reuse
it. No behaviour change.
