The MMC and network subsystems must be present to use device paths for
them. Add the missing checks.

Shim is a program which normally comes before U-Boot in the boot
process. But when the app runs first, it can sometimes chain Shim since
that is what is contained within the bootaa64.efi file, for example.
Add a simple command for dealing with shim. For now it only supports
enabling verbosity.

Add a function which looks through a device path and tries to figure out
the corresponding name (e.g. 'nvme' and uclass ID. This can be useful
for showing a short summary of the device path.

Add proper device-path handling for UCLASS_EFI_MEDIA devices in both
dp_size() and dp_fill() functions. This enables EFI applications to use
firmware device-paths for media devices accessed through the EFI block
I/O protocol.
Add some debugging while we are here.

The global-variable GUID is already set in the common device_path.c file
but its declaration is only in the efi_loader header.
Move it and also move over the FDT GUIDs.

This call seems to have been added in an unrelated commit, likely to fix
a bug:
046fe7b507 ("efi_loader: efi_dp_from_file() expect UTF-8 path")
With standard boot we don't need to call efi_set_bootdev(). Also this
function is not available in the EFI app.
So for now, add a condition, to avoid a build error in the x86 app when
CONFIG_EFI_BINARY_EXEC is enabled.

While this doesn't really affect anything in practice, it is better to
deal with an incorrect use of this function (calling it with a UCLASS
which is not enabled).
Add a break after the UCLASS_BLK case, to help this.

Fixes: a48a8929de ("efi: Move most of efi_device_path into lib/efi")
The conversion to using a size variable was missing a break statement
for the BLK case. Fix it.

Most of these utility functions are useful for the app, so move them
into the common directory.
Move the GUIDs used by this file from their various other location, so
they are available to the app, even if it doesn't enabled EFI_LOADER
Fix the rather large number of checkpath warnings in this file, except
for the lwip one, best left to the maintainer to sort out.
One noteable change is adding a return value to dp_fill() for the case
where an option is not enabled but its uclass is referenced. This
presuambly never happens during execution, since if the uclass is not
supported there can be no device in that uclass and therefore nothing
will ever request its path. So just handle this like an invalid device.
