[Dace] Default to BuildAndRun

[FlorianDeconinck]

Description

The default DaceConfig build was flipped to Run when Python was removed. But Run will force looking at the cache directory and in two-step init (like Pace) this is too early as we haven't read the configuration entirely yet.

This yet another echo of the (mine) bad design of DaceConfig. This PR will help is just a rubber band before we rebuild the entire orchestration build system.

How has this been tested?
