Benjamin Otte 7fa159e94a vulkan: Cache VkRenderPasses in render object 
Instead of recreating the same renderpass object in every frame and for
every offscreen, just reuse it.

Technically, we can save this per-renderer or even per-display (it
should really be cached by VkDevice), but we have no infrastructure for
that.
