Suggestion Add Formatting Options To CppScaffolding.cs

[std-nullptr]

Another suggestion I had is adding formatting options to CppScaffolding.cs that allows you to output il2cpp-types.h in either C, C++, or both. Right now the default is to have both of them, but in a regular project there can be several thousand enums. While this normally wouldn't be a problem but some people I have worked with who have older/slower computers have issues with IntelliSense taking forever to process il2cpp-types.h and erroring out.
