fix(qtdeclarative): properly generate qtquick-config.h features

The qtquick-config.h file was being generated empty by the cmake
build, causing 'division by zero in #if' errors in downstream
consumers (SDDM, KWin) because QT_CONFIG(quick_shadereffect) and
QT_CONFIG(quick_draganddrop) were undefined.

Two fixes:
1. Explicitly enable QT_FEATURE_quick_shadereffect and
   QT_FEATURE_quick_draganddrop in the cmake configuration.
2. Add a safety net that regenerates qtquick-config.h with the
   required feature definitions if cmake produces an empty file.
