Add a generic GRUB_PE32_MAGIC definition for the PE 'MZ' tag and delete
the existing one in arm64/linux.h.
Update arm64 Linux loader to use this new definition.

There is nothing ARM64 (or even ARM) specific about the efi fdt helper
library, which is used for locating or overriding a firmware-provided
devicetree in a UEFI system - so move it to loader/efi for reuse.
Move the fdtload.h include file to grub/efi and update path to
efi/fdtload.h in source code referring to it.

grub_efi_allocate_pages Essentially does 2 unrelated things:
* Allocate at fixed address.
* Allocate at any address.
To switch between 2 different functions it uses address == 0 as magic
value which is wrong as 0 is a perfectly valid fixed adress to allocate at.
Expose a new function, grub_efi_allocate_pages_real(), making it possible
to specify allocation type and memory type as supported by the UEFI
AllocatePages boot service.
Make grub_efi_allocate_pages() a consumer of the new function,
maintaining its old functionality.
Also delete some left-around #if 1/#else blocks in the affected
functions.

We only support FDT files with EFI on arm and arm64 systems, not
on x86. So move the helper that finds a prepopulated FDT UUID
into its own file and only build it for architectures where it
also gets called.

Searching for a device tree that EFI passes to us via configuration tables
is nothing architecture specific. Move it into generic code.

Define
* GRUB_EFI_PERSISTENT_MEMORY (UEFI memory map type 14) per UEFI 2.5
* GRUB_MEMORY_PERSISTENT (E820 type 7) per ACPI 3.0
* GRUB_MEMORY_PERSISTENT_LEGACY (E820 unofficial type 12) per ACPI 3.0
and translate GRUB_EFI_PERSISTENT_MEMORY to GRUB_MEMORY_PERSISTENT in
grub_efi_mmap_iterate().
Includes
* adding the E820 names to lsmmap
* handling the E820 types in make_efi_memtype()

Exclusive open on SNP will close all existing protocol instances which
may disable all receive filters on interface. Reinstall them after we
opened protocol exclusively.
Also follow UEFI specification recommendation and stop interfaces when
closing them:
Unexpected system errors, reboots and hangs can occur if an OS is loaded
and the network devices are not Shutdown() and Stopped().
