The efi_handle_dump command is currently used when barebox is built as
payload, but it's also useful when running as a loader to list handles
and their protocols. Move the code into a common area to make it
accessible in both configurations.

For development, it has proven very useful to be able to load the same
barebox binary both as EFI loader and EFI payload and debug the
interaction. For this to work, we need to mark all current EFI payload
initcalls as such to avoid running them when barebox is not running
as EFI payload.

With the loader support, efi.h will grow quite a bit. To avoid having to
include it always, lets move the base definitions into a new
<efi/types.h> and make the different <efi/*.h> headers self contained.

The '_d' suffix was originally meant to distinguish barebox struct
names from Linux struct names. struct driver doesn't exist in Linux,
so we can rename it and remove the meaningless suffix.

The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

boot_services::open_protocol supports opening protocols exclusively.
A protocol that is opened exclusively can not be used anymore by
an application that is called via boot_services::start_image.
We want to open the SNP protocol exclusively in the next step. That
would mean a chainloaded barebox could no longer use the SNP protocol
because it's exclusively opened by the current barebox already.
To work around this a efi_drv::dev_pause and efi_drv::dev_continue is
introduced. The former is called before an application is started and
the latter right after an application has exited. This will be used
by the SNP network driver to enter/leave exclusive mode.

We have at least two places where we check if a efidev has a particular
guid and a follow-up commit will introduce a third place.
So lets factor it out into a helper.

We already determine the boot source variable at core init level, but so
far we didn't populate the instance because the numbering of the block
devices isn't known that early. Introduce a helper to check if a block
device is the boot source and if it is, have the block device driver
populate the missing boot source instance.
