Mention wxLocale in wxNumValidator documentation.

Browse Source 
Using setlocale() can thoroughly confuse wxNumValidator because it results in
a mismatch between the decimal and/or thousands separators it uses, returned
by wxLocale, and the actual separators in the strings, formatted by the CRT.

So mention in the documentation that using setlocale() is a bad idea.

Closes #12970.

When the validator displays integers with thousands separators, the
