Add the end to end testing infrastructure required to verify the liveupdate feature. This includes a custom init process, a test orchestration script, and a batch runner. The framework consists of: init.c: A lightweight init process that manages the kexec lifecycle. It mounts necessary filesystems, determines the current execution stage (1 or 2) via the kernel command line, and handles the kexec_file_load() sequence to transition between kernels. vmtest.sh: The primary KTAP-compliant test driver. It handles: - Kernel configuration merging and building. - Cross-compilation detection for x86_64 and arm64. - Generation of the initrd containing the test binary and init. - QEMU execution with automatic accelerator detection (KVM, HVF, or TCG). run-vmtests.sh: A wrapper that runs vmtest.sh for each LUO test across supported architectures, providing a summary of pass/fail/skip results.
