Add support for QEMU/libvirt platform.

[cwize1]

Add basic support for running LISA framework on Linux platform
using QEMU via the libvirt API. This includes succesfully running
the Microsoft T0 tests against the CBL-Mariner image.

We manage commits to reflect the code changes in history. It needs each commit is meaningful and independent (well, it looks like at least). Please try to use git add/reset -p, git rebase -i origin/main and other commands to pick, sort the changes. For some big change like init a platform, it doesn't need a separated change. But for some changes, which involves the platform, it's better to make it meaningful, and small.

Yeah, it's ready to merge (assuming no further comments). Though I do plan on adding additional features (serial console, data disks, etc.) over time.

Thank you. I will double check if. If there is no other comment, I will approve and merge it.
