Use helper functions efi_created_handle and efi_add_protocol for creating the console handles and instaling the respective protocols.
This change is needed if we want to move from an array of protocols to a linked list of protocols.
Eliminate EFI_PROTOCOL_OBJECT which is not used anymore.
Currently we have not defined protocol interfaces to be const. So efi_con_out and efi_console_control cannot be defined as const.
