This patch factors resource usage tracking so it is separate from command validation, allowing the bulk of command validation to be completely skipped. In DrawCallPerfRun/Vulkan_DynamicPipeline_DynamicBindGroup, disabling validation cuts roughly 74 nanoseconds (20%) of CPU time, per draw. In DrawCallPerfRun/Vulkan_DynamicBindGroup, disabling validation cuts roughly 35 nanoseconds (17%) of CPU time, per draw. In DrawCallPerfRun/Vulkan_MultipleBindGroups, disabling validation cuts roughly 45 nanoseconds (14%) of CPU time, per draw.
