Vulkan: Avoid redundant work in updateFullActiveTextures ContextVk keeps mActiveTexturesDesc, which gets updated by UpdatePreCacheActiveTextures(). This is only used for cache lookup. When there is a cache miss, we end up call updateFullActiveTextures() which recomputes DescriptorSetDesc again, which is redundant work. This CL removes mActiveTexturesDesc from ContextVk. UpdatePreCacheActiveTextures has been changed to be a DescriptorSetDescBuilder method so that it can directly update the mDesc. updateFullActiveTextures has been renamed to updateActiveTexturesForCacheMiss which avoid mDesc calculation. updateFullActiveTextures is still kept for now which will be used in next CL when cache is disabled.
