Add a special symbol which is defined only if the icons and other images (e.g. cursor) are in the separate resource files and don't need to be embedded as XPMs in the main program. This makes the checks more clear and more customizable as it's enough to change wxHAS_IMAGES_IN_RESOURCES definition instead of changing many platform checks. Closes #14050. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@70789 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
