Vulkan: Support different SCBs for outside and inside RP The render pass command buffers are generally much larger than outside render pass command buffers, and their allocation sizes and frequencies differ. This change allows choosing between ANGLE and Vulkan secondary CBs independently for outside and inside render pass commands, as part of an investigation to understand which implementation performs best for each. Switching to Vulkan secondary command buffers is still slower. In the ball park, switching outside render pass SCBs doesn't seem to make much difference, while switching render pass SCBs duplicates the frame's CPU time.
