Vulkan:Add SecondaryCommandBuffer class SecondaryCommandBuffer is a CPU-side command buffer construct intended to delay allocation/construction of GPU-side command buffers until absolutely necessary. Initially ANGLE was batching commands into Vulkan secondary command buffers and then submitting those command buffers when rendering was required. On at least some devices we saw two areas of overhead that SecondaryCommandBuffers are intended to reduce: 1. Commands in secondary cmd buffers taking longer than equivalent commands in a single primary cmd buffer. 2. Allocation/free/reset overhead of the secondary command buffers was a hotspot for some workloads.
