Add EFI platform bootable images for x86 platforms. These images can
also boot from legacy BIOS platform.
EFI System Partition need to be fat12/fat16/fat32 (not need to load
filesystem drivers), so the first partition of EFI images are not ext4
filesystem any more.
GPT partition table has an alternate partition table, we did not
generate it. This may cause problems when use these images as qemu disk
(kernel can not find rootfs), we pad enough sectors will be ok.

(cherry picked from commit a6b7c3e672)
CONFIG_EFI_VARS has been disabled in
64bit x86 target in 2018 by the following commit
b0a51dab8c
the same reasons apply to Generic target, so
now it's disabled here too.
Leaving it enabled is also blocking compile as
a new symbol was added
EFI_CUSTOM_SSDT_OVERLAYS
that depends from CONFIG_EFI_VARS
and the build system stops and waits for
user input on what to do about it.
The Legacy and Geode targets never
had any EFI_xxx configs enabled so they
don't have this issue
