Update __cpp_concepts macro (#87998)
After discussion with a few others, and seeing the state of our concepts
support, I believe it is worth trying to see if we can update this for
Clang19. The forcing function is that libstdc++'s `<expected>` header is
guarded by this macro, so we need to update it to support that.
