dhcp: make DHCP6_OPTION_* enum public

libsystemd-network provides the public function
sd_dhcp6_client_set_request_option() to enable the request of a given
DHCP option. However the enum defining such options is defined in the
internal header dhcp6-protocol.h. Move the enum definition to the
public header sd-dhcp6-client.h and properly namespace values.
