Add C++20-style starts_with()/ends_with() functions to wxString

Browse Source 
C++20 introduces these two functions, along with some overloads, to
std::string. Add similar functions to wxString, which simply call the
already existing StartsWith() and EndsWith().

Closes https://github.com/wxWidgets/wxWidgets/pull/1452
