efi_loader: console support for color attributes

Shell.efi uses this, and supporting color attributes makes things look
nicer.  Map the EFI fg/bg color attributes to ANSI escape sequences.
Not all colors have a perfect match, but spec just says "Devices
supporting a different number of text colors are required to emulate the
above colors to the best of the device’s capabilities".
