D7304: Do not leak symbols of pimpl classes, protect with Q_DECL_HIDDEN

Restricted Application added projects: Plasma on Wayland, Frameworks.
Restricted Application added subscribers: Frameworks, plasma-devel.

REVISION SUMMARY
  Nested classes inherit the visibility of their outer class,
  so all the KClass::Private symbols have also been exported
  if the ones of KClass were.
  
  See also https://phabricator.kde.org/D7279

TEST PLAN
  Ran nm -DC to list symbols
  Only changed visibility of classes defined in .cpp files, so no client code should be affected.

REPOSITORY
  R127 KWayland
