[clang] [Clang][docs] Update extension documentation (PR #75150)

[Nikolas Klauser via cfe-commits]

https://github.com/philnik777 created https://github.com/llvm/llvm-project/pull/75150

This is back-ported to C++03 now, since clang accepts C++11 attributes in C++03. https://godbolt.org/z/f7xG18bdE
