[NFC] Consistenly use commented and annotated ScopPass functions

  The changes affect methods that are part of the Pass interface and
  include:
    - Comments that describe the methods purpose.
    - A consistent use of the keywords override and virtual.
  Additionally, the printScop method is now optional and removed from
  SCoP passes that do not implement it.
