grub: shuffle packaging for aarch64 builds

Even in grub-efi platforms we need to build grub for the the common
tools. On x86 this isn't a problem because grub builds legacy boot and
grub-efi builds EFI, but on aarch64 there is no legacy boot supported by
grub.

To ensure that the common tools are built the grub recipe also builds
EFI binaries, but this now means that grub and grub-efi ship the same
binaries.

oe-core 933286 fixed this conflict by deleting the binaries from
grub-efi and putting the aarch64 modules into grub-common (relying on
dependencies to pull grub-common in).  This seems backwards: grub-efi no
longer contains the binaries and they're in different packages on arm or
x86.  Also, SDK generation is broken as the grub package itself is now
empty as the binaries are in grub-common.

Resolve all of these issues by reversing the logic:  grub-efi is the
package which holds the EFI binaries on all platforms. grub only builds
for EFI on aarch64 as a way to build the common binaries, so delete them
in that recipe to avoid conflicts.  And finally as the grub recipe is
empty on aarch64 but needed by dependencies, set ALLOW_EMPTY.
