integrate hxcpp-debug into kodestudio for debugging in CPP mode

[sangohan]

there is an existing vscode plugin/extension which integrates a hxcpp debug mechanism into vscode (see https://github.com/jcward/vscode-hxcpp-debug).

It would be nice to integrate this into kodestudio so that the debug can also be done using hxcpp (i would assume most people are going to use the cpp target rather than the js target, and is only doing the js target for fast dev loop during development).

AFAIK hxcpp-debug still doesn't work properly on all platforms. The moment that changes I will integrate it (actually Kode Studio already bundles vscode-hxcpp-debug but currently I do not compile it).
Meanwhile Kha makes it easy to debug target specific problems in Visual Studio and XCode (when you have target specific problems you probably want to see the C++ code anyway).
