Split SkPicturePlayback out of SkPictureData

Browse Source 
This splits the playback functionality out of SkPictureData. The old SkPictureData::draw method is pulled out along
with its supporting functions as verbatim as possible. Some follow on CLs will be required to:

   re-enable profiling in the debugger (and remove the vestiges of SkTimedPicture)
   re-enable display of command offsets in the picture (this should probably wait until we've switched to SkRecord though)
   Clean up CachedOperationList (maybe fuse with SkPicture::OperationList)
   Split SkPicturePlayback into a base class and two derived classes
   Implement parallel version of GatherGPUInfo for SkRecord

Landing this is blocked on removing Android's use of the abortPlayback entry point.
