flowey: add --use-local-deps option to build-igvm, add local request variant to download_openvmm_deps

[justus-camp-microsoft]

In order to get to reproducible builds, we're going to need all nodes that currently download something at build time to allow for Nix to download them instead and then specify the path at which they've been downloaded. There are several nodes that don't currently have Local override request variants. I've started with download_openvmm_deps (renamed to resolve_openvmm_deps, but have also plumbed a --use-local-deps command line parameter to build-igvm for testing locally.

Pull Request Overview

This PR adds support for using locally-downloaded dependencies in the flowey build system as a step toward reproducible builds. The main change renames download_openvmm_deps to resolve_openvmm_deps and adds a LocalPath request variant alongside the existing Version variant. A new --use-local-deps CLI option is added to the build-igvm pipeline for local testing.

Key changes:

• Renamed download_openvmm_deps module to resolve_openvmm_deps to reflect its dual purpose (download or resolve local paths)
• Added LocalPath request variant with logic to resolve dependencies from local x64/aarch64 subdirectories
• Added --use-local-deps and --custom-openvmm-deps CLI options to build-igvm pipeline for testing with local dependencies
