  Add optimization to defer clear calls.
  
  This change adds a new SubresourceUpdate struct that will hold either
  an update for a clear call or a texture upload in an ImageHelper's
  update queue.
  
  It also adds logic to defer clear calls similar to Vulkan's,
  where clears are deferred if there is not an active render pass.
  Draw based clears are not yet supported, so the optimization does not
  handle those yet.
