  Capture/Replay: Implement more state for mid-execution replay.
  
  Includes much more state serialization. Notably Vertex Arrays were
  missing as well as multiple GL render states. Also fixes many
  serialization bugs. For example, we would not be using the correct
  client array and pack/unpack state in the mid-execution capture. Also
  depth/stencil attachments were missing from the capture.
  
  Also fixes the replay sample to work with non-zero starting frames.
  
  With these fixes we can run mid-execution replay of the T-Rex demo.
