CheckIncludeFiles: Add LANGUAGE CXX option

Ported from CheckIncludeFiles.cmake

I wasn't sure whether to add any tests or update the documentation in CheckIncludeFile{,CXX,s}.

Topic-rename: CheckIncludeFiles-language-CXX

changed the description

Rather than introducing a new module, we should add LANGUAGE <lang> option to the existing macro. This will be more extensible to other languages later (e.g. Fortran).

This is done in CheckTypeSize, CheckStructHasMember, and CheckIPOSupported. The singular CheckIncludeFile and CheckIncludeFileCXX modules are only separate for historical reasons. The same change could be made to CheckIncludeFile.

That seems very sensible but involves a significant amount of refactoring, which I'll try and get right.

OK - it's actually less than I thought. I've borrowed from CheckStructHasMember and CheckFunctionExists.

Thanks. Please extend Tests/RunCMake/CheckModules/RunCMakeTest.cmake with cases covering this module.
