Define wxStrtox() overloads taking nullptr

Browse Source 
Instead of specializing wxStrtoxCharType and then testing whether endptr
is null, just define separate, and simpler, overloads of wxStrtox()
functions taking nullptr_t -- we can avoid the unnecessary test
completely in this case, as nullptr is, by definition, always null
anyhow.

Also add a test of using wxStrtol() with nullptr too.

This should fix the build with older gcc and MSVS versions.
