This CL updates the infra scripts used to create the CIPD asset for
SVG's corpus on gold to download and include image resources.
Summary of changes:
- Change svg_downloader.py input argument to more generic name
- Add --keep_common_prefix arg to svg_downloader.py to preserve the
directory hierarchy for images, needed for the W3C test suite.
- Update infra SVG create.py script to download images
- Add svg_images.txt file with a list of the images we need for the W3C
test suite already in gold.
Actually updating the corpus will happen in a separate CL.
