Thanks to the introduction of GPT partition table support in genimage,
this commit improves the pc_x86_64_efi_defconfig to remove the use of
the custom script creating the image.
Tested in QEMU, not on a physical device.
So:
- revert commit fee29b05bb7db25e37c8a5175ce00dc712554edf[1]
- add GPT support
- tweak shell script to add the correct UUID in genimage config.

Following commit fee29b05bb
("configs/pc_x86_64_efi: use a GPT partition table"),
board/pc/grub-efi.cfg is no longer used anywhere: the
post-image-efi-gpt.sh script generates the grub configuration.
Also, since post-image-efi-gpt.sh generates a grub configuration file
that uses the root filesystem partition UUID as the root= kernel
argument, the instructions in the readme.txt file to tweak root= from
/dev/sda2 to /dev/vda2 is no longer relevant. This was noted in the
commit log of fee29b05bb:
The root filesystem location is passed to the kernel by a partition
UUID, so it is possible to boot on QEMU, directly from the disk image,
or dump the image to a physical device.
Fixes: #11841

This simplifies the pc configs and respective post image scripts to use
the shared genimage script and separate grub config files.
Separate grub files are cleaner to maintain and easier to copy and
modify, for example to support booting the pc defconfigs in qemu.
