Languages: Add support for Objective-C
Add entries in Modules and Modules/Platform to support Objective-C compiler determination and identification. Add Modules to check Objective-C compiler flags, source compilations, program checks, etc... Use OBJC as the designator of the language, eg: project(foo OBJC) Add various tests for Objective-C language features. Add tests to preserve C++ handling of .m and .mm files when OBJC is not a configured language. Co-Authored-By: Cristian Adam <cristian.adam@gmail.com>
