Add a compiler flag to report time spent on GPU transformations, add new GPU perf tests

This PR adds --report-gpu-transform-time developer flag to the compiler.

Then, adds the following GPU performance plots:

  • One that measures GPU transform time in the compiler
    • This compiles jacobi.chpl and math.chpl where the second one has a ton
      of gpuized loops
  • One that measures end-to-end compilation time for those two tests with --fast
  • An empty kernel launch plot
    • This is supported by a new test that measures sustained kernel launch
      performance for an empty foreach
    • The test's correctness mode ensures we launch expected number of kernels
  • Finally, a plot for the stream prototype we wrote quite some time ago

[Reviewed by @stonea]

Test:

  • new plots are generated with -perflabel gpu-

  • gpu/native correctness

  • standard linux64 correctness
