REVISION SUMMARY
  The new touch gestures activated for the same actions as configured for
  mouse pointer actions. This has disadvantages as the only configured
  default screen edge action cannot be triggered (corner) on touch. On the
  other hand setting a default touch gesture would be rather annoying with
  pointer as a default.
  
  So overall it makes sense to split the actions and have dedicated pointer
  and dedicated touch actions.
  
  This change introduces the first part of it and splits the handling in
  general. We now have:
  
  Activates for pointer and touch:
  
  - client (auto-hiding panels)
  
  Activates for pointer only:
  
  - the configured action
  - virtual desktop switching
  - callbacks
  
  Activates for touch only:
  
  - the new touch action
  
  The touch actions are implemented similar to the pointer actions which
  slight improvements in the code which will be backported to the pointer
  actions.
  
  Introducing callbacks will be the next step. I plan to do it a little bit
  different by using QActions as that's what KWin internally uses for
  everything except screen edges.

TEST PLAN
  Manual testing and improved auto tests
