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.
