Use the same version scheme as other Qt modules

After trying to get rid of all private header includes, the last
standing one is qplatformnativeinterface.h even though its name
previously suggested that it isn't private.

This would be a complicated piece to expose publically in a way both
flexible and binary compatible, and is a task heavy enough to
justify committing to follow Qt's release cycle.

The QML import version remains to 1.0 and will be incremented the
same manner as QtQuick itself does.
