Fix the rebase onto the native engine: Vulkan frontend staging, RR gating, lazy RR debug stages

The native Vulkan frontend stages packed rows and refuses Ray Reconstruction, whose guides it
does not stage. make_ptx loads the denoiser's per-layer debug stages only when one is
requested, so builds without the denoiser's PTX corpus (preset L's texture kernels) work.
