Pull request overview
This PR updates Flowey infrastructure to consume the upcoming split microsoft/openvmm-deps artifact layout, separating the main dependency archive from per-kernel Linux test payload archives.
Changes:
- Adds Linux test kernel version selection to
download_openvmm_deps. - Switches OpenVMM deps extraction/downloads from
.tar.bz2to split.tar.gzartifacts. - Regenerates CI workflow YAMLs for the new Flowey graph.

Post-split, no `OpenvmmDepFile` variant has an arch-dependent filename (the only ones that did — kernel and initrd — moved out into their own nodes). Drop the now-dead `_arch` parameter and update both call sites. Addresses review feedback on microsoft#3483. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

openvmm-deps 0.3.0 ships three .tar.gz artifacts per arch: - openvmm-deps.<arch>.<ver>.tar.gz: sdk + dbgrd + shell + petritools - openvmm-test-initrd.<arch>.<ver>.tar.gz: shared test guest-userland initrd - openvmm-test-linux-6.1.<arch>.<ver>.tar.gz: 6.1 LTS test kernel image (vmlinux/Image), bzImage (x86_64), and final config Add matching flowey resolve nodes: - `resolve_openvmm_deps` (slimmed): exposes individual files from the main openvmm-deps tarball via `OpenvmmDepFile` (Dbgrd, Shell, Sysroot, PetritoolsErofs). - `resolve_openvmm_test_initrd`: returns the path to the shared `initrd` file. Parameterized by arch. - `resolve_openvmm_test_linux_kernel`: returns paths to files in the per-(arch, kver) test kernel archive via `OpenvmmTestKernelFile` (`Kernel` for the primary vmlinux/Image image, `BzImage` for the x86_64-only bzImage). Parameterized by `(file, arch, kver)`. The `LinuxTestKernelVersion` enum currently contains just `Linux6_1`. All three nodes accept either a `version` (download from the public GH release with `needs_auth: false`) or `local_paths` (use a pre-extracted directory on disk). The kernel resolver dedupes archive download + extraction on `(arch, kver)`, so requesting both `Kernel` and `BzImage` from the same archive only extracts once. Add `flowey_lib_common::_util::extract::extract_tar_gz_if_new`, mirroring the existing `extract_zip_if_new` / `extract_tar_bz2_if_new` helpers. Wire `init_vmm_tests_env`, `init_openvmm_magicpath_openvmm_deps`, and `build_openhcl_igvm_from_recipe` to request the kernel + initrd from the new nodes. Pin `OPENVMM_DEPS = "0.3.0-29"`. Pipeline YAMLs regenerated. Companion: microsoft/openvmm-deps#62 (merged as v0.3.0-29). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Parameterized by(file, arch, kver). Archive download + extraction is deduped on(arch, kver)so requesting bothKernelandBzImagefrom the same archive only extracts once. TheLinuxTestKernelVersionenum currently contains justLinux6_1;DEFAULT_LINUX_TEST_KERNEL_VERSIONis exported for callers that don't care which kernel they get. Future kernel lines are added by extending the enum.All three nodes accept either a
