Having an EFI_RNG_PROTOCOL without a backing RNG device leads to failure
to boot Linux 5.8.
Only install the EFI_RNG_PROTOCOL if we have a RNG device.

Install the EFI_RNG_PROTOCOL implementation for it's subsequent use by
the kernel for features like kaslr.

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.

Rename variables to make it clear they refer to the Unicode collation
protocol identified by the EFI_UNICODE_PROTOCOL2_GUID.

The device path to text 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.

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.

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.

By using InstallMultipleProtocolInterfaces() the coding for installing
protocol interfaces on the root node can be simplified.

We should not install the HII protocols on every loaded image. It is
sufficient to install them once on the 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.
