Don't allow wxSpinCtrl range to include negative values if base != 10 (wxOSX)

For the sake of consistency with another ports only unsigned
hexadecimal numbers should be supported. To do so we need
to prevent:
- Setting a range including negative values if base == 16.
- Setting base != 10 if current range includes negative values.

Closes #18805.
