Use add_shaders with CMake in some examples

Take the most obvious candidates, to which users typically turn
when getting started with ShaderEffect or QSGMaterial:

shadereffects
scenegraph/custommaterial
scenegraph/twotextureproviders

As with the parent patch that ports and updates embeddedinwidgets and
quickwidget/qquickviewcomparison to use the proper CMake machinery, we
still need to keep the .qsb files for the sake of qmake. compile.bat and
similar scripts are however removed now. With CMake the .qsb files are
not needed and are autogenerated at build time. Once qmake support
disappears from the examples, the .qsb files can be removed as well.
