x86: generate EFI platform bootable images
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.
