Before the render graph was introduced we relied on a submission resource tracker that allowed to resuse resources in the next frame. With the introduction of the render graph we slowly migrated the resource tracking to the render graph and eventually also moved the whole discard pools to the submission runner. There was still one part that 'used' the legacy resource tracker, but actually didn't as it never reused resources. This PR removes the resource tracker and migrate the push constants to use the render graph to update a single buffer per shader.
