Tor Arne Vestbø 97665c9615 Windows: Don't rely on top level QWindow to scale children on DPI change
The native size of a QWindow on Windows is the logical size of the window
times the window's device pixel ratio. We manage this relationship
for top level windows via the WM_GETDPISCALEDSIZE message, and during
WM_DPICHANGED we then applied the same scale to child windows.

This is problematic in the case where a child window does not have
a QWindow parent, so instead of scaling all children when the parent
gets a WM_DPICHANGED message, we scale each individual child in the
child's WM_DPICHANGED_AFTERPARENT message.

Task-number: QTBUG-103383
