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.

MS and Apple guidelines mention ellipses should generally be used when a command needs additional information from the user before the operation can execute. This is not the case for showing an about dialog so the ellipses have been removed.
