qmake: allow building without KDE Frameworks 5 (CONFIG+=no_kf5)

Browse Source 
The CMake build has supported building without KF5 since the Qt-only
replacements landed in sources/ui/nokde (BUILD_WITH_KF5=OFF). The qmake
build had no equivalent: qelectrotech.pro hard-coded

    QT += ... KWidgetsAddons KCoreAddons ...

so a machine without KF5 fails at configure time with

    Project ERROR: Unknown module(s) in QT: KWidgetsAddons KCoreAddons

This is the error reported in discussion #393, where a contributor gave up
trying to build on Windows with Qt 5.15.2 / MinGW. Deleting the two modules
by hand (the obvious workaround) then fails at link time with undefined
references to KAutoSaveFile, because the nokde sources are never compiled.

Mirror the four things CMake does when BUILD_WITH_KF5=OFF:

  - define BUILD_WITHOUT_KF5 (the sources already guard on it)
  - add sources/ui/nokde to INCLUDEPATH
  - compile the three nokde replacements (KAutoSaveFile, KColorButton,
    KColorCombo)
  - drop KWidgetsAddons/KCoreAddons from QT

The default build is unchanged: without CONFIG+=no_kf5 the KF5 modules are
still required and sources/ui/nokde is not on the include path.

Usage:

    qmake CONFIG+=no_kf5 qelectrotech.pro
