Changes look good to me, but please also extend the CI to do a cross-build for LoongArch. The RISCV test can be used as a reference: https://github.com/containers/libkrunfw/blob/main/.github/workflows/cross-build-riscv64.yml |

This PR adds the minimum libkrunfw changes required to support LoongArch in the current single-vCPU libkrun configuration.
Changes in this PR:
Make the build process recognize
ARCH=loongarch, useloongarch64as the guest architecture, and bundlearch/loongarch/boot/vmlinux.efi.Extend
bin2cbundle.pyto add thelinux_pebundle type so that the LoongArch EFI kernel image is embedded with the correct load and entry addresses.Add
config-libkrunfw_loongarch64to the bundled Linux 6.12.76 guest kernel.This PR is specifically limited to the initial enabling of LoongArch for single-vCPU guests.
LoongArch SMP support still relies on additional host-side KVM IPI processing and client-side interrupt/SMP startup, but as of the current kernel version used by libkrunfw, it is not supported and will require separate patches or waiting for the kernel version to be updated to 6.13. These will be handled separately.
