b1b782d306 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.

Most of Rob's original patch is already merged. Only the deprecated
protocol is missing. Rebase it and make it configurable.

64b5ba4d29 efi_loader: make device path to text protocol customizable
The device path to text protocol is not needed for EBBR compliance. So
let's make it a customizable option.

334997356e efi_loader: make Unicode collation protocol customizable
The Unicode collation protocol is not needed for EBBR compliance. So let's
make it a customizable option.

The Unicode capitalization table is only needed by this protocol. So let it
depend on the Unicode collation protocol.

84a918e8ce efi_loader: LoadImage() check parent image
If the parent image handle does not refer to a loaded image return
EFI_INVALID_PARAMETER.
(UEFI SCT II 2017: 3.4.1 LoadImage() - 5.1.4.1.1)

Mark our root node as a loaded image to avoid an error when using it as
parent image.

a2a4bc3b09 efi_loader: export root node handle
This is a preparatory patch.
The root node handle will be used as a dummy parent handle when invoking
an EFI image from bootefi/bootmgr command.

8ec7d5d355 efi_loader: assign HII protocols to root node
We should not install the HII protocols on every loaded image. It is
sufficient to install them once on the root node.

4e6b5d6503 efi_loader: create root node
Currently we assign a lot of protocols to loaded images though
these protocols are not related to them. Instead they should be
installed on a separate handle. Via the device path it is the
parent to the devices like the network adapter.
