Vadim Zeitlin ffc3168f6f Make wxFontBase::operator==() symmetric by taking wxFontBase 
Taking wxFont here resulted in a potential ambiguity when comparing
wxFont objects, at least according to clang 12 in C++20 mode.

Avoid this by just taking wxFontBase here, as now the operator is fully
symmetric, rather than exactly matching only (wxFontBase, wxFont) and
matching (wxFont, wxFont) either directly or with reversed arguments
order.
