Copy the tarball content

[premun]

Context

As part of the tarball generation process, we copy this content folder and put it in the root of the tarball. We need to bake this step into the VMR assembly process so that these files are in place for source build to work.

Goal

For this step of the tarball generation process, we need to find a counterpart in the VMR and decide when it will happen, then implement it.

Things to consider

• Since we will have the VMR side by side with the tarball generation, we will need to keep the files synchronizing every time we pull dotnet/installer into the VMR.
• At some point, we would like to start making changes in the VMR itself and we should have a plan for how we will deal with conflicts there (we should learn about the conflicts there in the first place).

[premun]

This one will be baked into the VMR initialization process and re-used from the tarball generation process
