Benjamin Otte 2aba50efa0 vulkan: Move the render ops to the Render
This is a massive refactoring because it collects all the renderops
of all renderpasses into one long array in the Render object.

Lots of code in there is still flaky and needs cleanup. That will
follow in further commits.

Other than that it does work fine though.
