Respect the per-item layoutSpacing() if the style uses that feature.
We move the QLayoutStyleInfo class out of the gridlayout engine to a common header file so that anchor layout also can utilize it. Due to that we now can have a per-item spacing we have to change the 'effectiveSpacing' argument of refreshSizeHints to just take a QLayoutStyleInfo pointer that we will later query for the actual spacing used.
