efi/libstub: Avoid efi_puts() for compile time constant strings

efi_puts() performs a UTF-8 to UTF-16 conversion on its input, as the
EFI console's native character set is UTF-16.

This is pointless for compile time constant strings, since we can
simply define those as UTF-16 to begin with. This takes slightly more
space, but removes any runtime handling of those strings, simplifying
the code.

Note that efi_puts() also performs LF to CR-LF conversion, so this needs
to be taken into account as well.
