D8316: Add a pure virtual method to Platform to describe the supported compositors

[Martin Flöser]

REVISION SUMMARY
  So far KWin does not know which Compositors the platform actually
  supports. This results in KWin happily trying to use the OpenGL
  compositor on fbdev or the QPainter compositor on hwcomposer although
  that is obviously going to fail as the platform doesn't support this.
  
  By adding a pure virtual method all Platforms can define what they
  support. In a later step the Compositor can use this to create an
  appropriate scene and also perform proper fallback handling in case the
  scene creation fails.

TEST PLAN
  Compiles

REPOSITORY
  R108 KWin
