versions: Track and add support for building TD-shim

TD-shim is a simplified TDX virtual firmware, used by Cloud Hypervisor,
in order to create a TDX capable VM.

TD-shim is heavily under development, and is hosted as part of the
Confidential Containers project:
https://github.com/confidential-containers/td-shim

The version chosen for this commit, is a version that's being tested
inside Intel, but we, most likely, will need to change it before we have
it officially packaged as part of an official release.

Fixes: #4779
