  Reduce variance in TextureUploadPerf.
  
  This reduces the test time to run in several ms instead of almost
  seconds per iteration. It allows us to use the perf test runner harness
  to check test performance more accurately by increasing the sample
  count.
  
  It first reduces the test iteration count to reduce total test time.
  It also refactors the test contents to not allocate new objects and
  memory with every test iteration. This gives a better sampling of what
  the test is obsering: texture upload performance.
  
  Also allows tests that like to track GPU time to be used with the NULL
  device option.
