Title:
Reconsider compressed kernels on arm64

Bug description:
Compressed kernel images were introduced in bug 1384955 to work around
some limits on old u-boot systems. This in turn broke grub-check-
signatures, meaning that while cloud images booted in secure boot, you
could not upgrade grub or install new kernels on secure systems as
that would trigger a "you have unsigned kernels" message. grub 2.06
also fails to boot the images, as it verifies before decompressing.
Work to fix grub to handle such images on arm64 for backward
compatibility is tracked in bug 1954683. This bug is to reconsider
whether the change is still necessary or could be removed in 22.04
such that we can have proper UEFI executables again.
