Update webpages_playback script and all page_sets to use new skpicture_printer benchmark

The purpose of this CL is to turn the RecreateSKPs bot green after
https://codereview.chromium.org/665193002/ lands.

Description of changes in this CL:
* After https://codereview.chromium.org/665193002/ lands we will no longer need to copy the archives and pagesets to telemetry's data directory, I removed the code that did this in https://codereview.chromium.org/655313003/
* page_sets now need unique class names. Updated all page_sets to have unique class names.
* Using the new --page_set_name and --page_set_base_dir and --also-run-disabled-tests parameters

LGTM.  I only looked at a random few of the page sets.

Manfred's https://codereview.chromium.org/665193002/ is not submitted yet, but I
am going to go ahead and submit this CL since the bot is broken anyway.
