Show the firmware vendor and revision to make it clear which firmware is
used, e.g. whether U-Boot is providing the boot services.
The output will look like
Firmware vendor: Das U-Boot
Firmware revision: 20241000

We need to support multiple digits in the parts of the UEFI verision
number. E.g.
EFI_SPECIFICATION_VERSION = (123 << 16) | 456
must be printed as
123.45.6

At present we use wide characters for unicode but this is not necessary.
Change the code to use the 'u' literal instead. This helps to fix build
warnings for sandbox on rpi.

We should consistently use the same name for protocol GUIDs as defined in
the UEFI specification. Not adhering to this rule has led to duplicate
definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID.
Adjust misnamed protocol GUIDs.
Adjust the text for the graphics output protocol in the output of the
`efidebug dh` command.

The UEFI spec defines that a line feed moves the cursor to the next line
and (only) a carriage return moves the cursor to the beginning of the line.
So we should issue CR LF when we want to get to the start of the next line.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Commit bbf75dd9345d0b ("efi_loader: output load options in helloworld")
introduced a const variable in efi_main() called loaded_image_guid which
got populated from a constant struct.
While you would usually expect a compiler to realize that this variable
should really just be a global pointer to .rodata, gcc disagrees and instead
puts it on the stack. Unfortunately in some implementations of gcc it does
so my calling memcpy() which we do not implement in our hello world
environment.
So let's explicitly move it to a global variable which in turn puts it in
.rodata reliably and gets rid of the memcpy().

We need to test if we pass a valid image handle when loading
and EFI application. This cannot be done in efi_selftest as
it is not loaded as an image.
So let's enhance helloworld a bit.
