[REG:6.2->6.3] qmake in static qt build takes much longer to handle resources

When using static build of Qt 6.3, using qmake is much slower than in 6.2 when the project file includes any resources. Each resource file increases the qmake call by 2-5 seconds.

This is reproducible with any Qt example, such as regularexpressions, that has qrc file in it:

RESOURCES += regularexpression.qrc

Adding more resource files increases the qmake call time.
