Avoid full normalization including wxPATH_NORM_LONG when adding files to
wxFileHistory as this can take a very long time when using network paths under
Windows.
Closes#13915.

GTK+ provides GtkRecentManager for this purpose since 2.10. Use it in
wxFileHistory if available. Integration is simple, we just add a file to
GtkRecentManager in addition to normal wxFileHistory handling.
A well-behaved GNOME application would use GtkRecentManager as the
primary store for recent files, so that it reflects when the user works
with supported files in another editor(s) too. But for now, this is much
better than no support at all.
