build: refactor out common build command components
We had some duplicated code between the basic runBuild and launchControllerAndRunBuild. This patch refactors out the common logic (since it's only really like to keep growing), and has runBuild call into either the controller or directly start the build depending on whether BUILDX_EXPERIMENTAL is set.
