Don't use all_video by default on UEFI (Closes: #1036019)

all_video depends on both video_bochs and efi_gop, which may conflict with each other, causing video corruption on UEFI.

Fix this by:

  • Taking upstream patch, which changes default grub.cfg not to load all_video (see the patch for details)
  • Changing build-efi-images not to include all_video

Full steps to reproduce bug: https://gitlab.com/qemu-project/qemu/-/issues/2562

This PR is important, because it is needed to unblock work to enable CONFIG_DRM_SIMPLEDRM as builtin in Debian kernels ( kernel-team/linux!1453 ), which itself is needed for @bluca's UKI work.

Please, upload new version to Debian archive after applying this PR
