This layer allows runtimes to be built on-demand but cached in a consistent and re-usable location on the system. It handles careful filesystem operations to ensure consistency even in the face of multiple versions and build configurations. This addresses a number of TODOs from the initial runtimes building on-demand, and sets the stage to scale up to more runtimes. This doesn't switch on-demand runtimes to be on by default, I wanted to wait and make that change as a separate step. --------- Co-authored-by: Geoff Romer <gromer@google.com>
