Make it possible to call wxStandardPaths::MakeConfigFileName() without
explicitly specifying the convention to use, to make it conform to the
documentation (previously this only worked when calling the
wxStandardPathsBase version of the method).
Closes#18106.
Use an enum instead of type-unsafe "int" for the second parameter of the
recently added wxStandardPaths::MakeConfigFileName().
This also avoids unnatural dependency of wxStandardPaths on
wxCONFIG_USE_SUBDIR constant defined in a higher level wxFileConfig class.
No real changes, but just make things a bit more robust and hopefully more
clear.
Previously wxStandardPathsCF was used for all Mac builds and it used
FSFindFolder() (CoreFoundation) calls in Carbon builds, but many hard coded
values in Cocoa builds. The Cocoa implementation uses NSFileManager and
NSBundle to retrieve the folder locations from the system.
