Supported compilers are Clang 5, GCC 7, Visual Studio 17, Xcode 9.3
Update Atlas alongside since the replacement APIs are c++17 only.
De-activate the StyledTextCtrl module of WxWidgets on mac, since that is
a wrapper around the Scintilla Text editor and doesn't compile with
C++17 (as it uses auto_ptr). We don't use the editor, so this is also a
win on the compilation time front.
Closes#5862
