Add wxDIR_NO_FOLLOW flag for wxDir iteration.

Browse Source 
This flag allows to avoid following the symbolic links during the directory
traversal. In particular, this means that links to the directories
(potentially outside the directory being traversed) are not considered as
directories at all when it is used, potentially avoiding surprises.

Closes #14542.
