Added tests to check setting of clipping region using device coordinates.
Tests of setting clipping region(s) with wxDC::SetDeviceClippingRegion() for transformed wxDC/wxGCDC (with changed device origin, logical origin and scale and with various renderers for wxGCDC) to check if all transformations are taken into account in the clipping box calculations. See #17596
