QWidgetTextControl: port to new-style connects (faster)
This speeds up creating a QGraphicsTextItem by 14% in an optimized build
Before: 0.070 msecs per iteration
After: 0.060 msecs per iteration
Those connects were showing up when profiling, because of the string
parsing that is necessary when using SIGNAL/SLOT macros.
The stacktrace was connect() => decodeMethodSignature() => argumentTypesFromString()
=> QArgumentType constructor => qMetaTypeInternal(const char*).
Pick-to: 6.3 6.2 5.15
