DM: add --serialize

Plus:
  - minor ReplayTask refactoring to share code with SerializeTask
  - move --replay to ReplayTask and --serialize to SerializeTask like WriteTask
  - when --writePath is given, write failures for Replay and Serialize tasks
  - function names have fewer blatant Skia style violations
