Add support for Objective-C and Objective-C++

[marksisson]

Brief Issue Summary

When including OBJC and OBJCXX languages in C++/C projects, vscode-cmake-tools is logging "Unknown language" warnings for C++/C language standard versions. These same C++/C language standards are used by Objective-C and Objective-C++ in CMake project.

Expected:

Objective-C and Objective-C++ are strict supersets of C and C++ respectively, and CMake added official support for these as languages in 3.16.5, there should be no warnings for associated C++/C language standard versions.
