Use the OLMv1 Downstreaming RFC and the downstream image build guidelines as a guide.

This issue will likely require some creativity and trailblazing to work out the exact mechanics of:

1. The downstream repository structure
2. The automation/scripts necessary to maintain the desired repository structure as the upstream project makes releases.

Ideally, we are able to re-use upstream scripts/Makefiles in the downstream build. But that may require upstream changes to accommodate expectations of the downstream build system. For example, we may need to re-organize the way build tools are downloaded/built because the downstream system does not allow binary sources, even for build tools.
