kd-11 00b0311c86 rsx/gl/vulkan: Refactoring and partial vulkan rewrite 
- Updates vulkan to use GPU vertex processing
- Rewrites vulkan to buffer entire frames and present when first available to avoid stalls
- Move more state into dynamic descriptors to reduce progam cache misses; Fix render pass conflicts before texture access
- Discards incomplete cb at destruction to avoid refs to destroyed objects
- Move set_viewport to the uninterruptible block before drawing in case cb is switched before we're ready
- Manage frame contexts separately for easier async frame management
- Avoid wasteful create-destroy cycles when sampling rtts
