Fix wxWithImages::GetImageLogicalSize() in wxGTK and wxOSX
Calling FromPhys() unconditionally on the image list size was wrong, we
want to use the logical size of the bitmap contained in wxImageList
which depends on its scale factor and is the same as its physical size
on platforms using DPI-independent pixels such as wxGTK and wxOSX.
This resulted in positioning the bitmaps incorrectly in wxListCtrl (and
almost surely wxTreeCtrl too).
