SkPDF: Re-use Jpeg Image Shaders

Also, de-dup shader better.

  - SkBitmapKeyFromImage function factors out image de-dup code.
  - SkPDFUtils::ToBitmap funtion factors out to-bitmap code
  - make_image_shader function now takes Image rather than Bitmap.

All tests render the same.  Some are significantly smaller PDFs.
