experimental skp_to_pdf_md5 program.

experimental skp_to_pdf_md5 program.

This program takes a list of Skia Picture (SKP) files and
renders each as a multipage PDF, then prints out the MD5
checksum of the PDF file.  This can be used to verify that
changes to the PDF backend will not change PDF output.

tricky -- SkString is utf8 which is a compressed form of Unicode, which has a
host of pain related to sorting strings...
