efi_loader: implement deprecated Unicode collation protocol
In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2 language codes existed. This protocol is not part of the UEFI specification any longer. Unfortunately it is required to run the UEFI Self Certification Test (SCT) II, version 2.6, 2017. So we implement it here for the sole purpose of running the SCT. It can be removed once a compliant SCT is available. The configuration option defaults to no. Signed-off-by: Rob Clark <robdclark@gmail.com> Most of Rob's original patch is already merged. Only the deprecated protocol is missing. Rebase it and make it configurable. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
