Richard Smith 09b79784dc Include the Carbon package name in the exported C++ namespace. (#7935) ...

When exporting `X` from Carbon package `Foo`, expose it to C++ with
fully-qualified name `Carbon::Foo::X`, not simply `Carbon::X`. This
ensures that C++ mangled names properly distinguish between same-named
Carbon entities in different packages.

Name *lookup* into `Carbon::` still uses the same rules as before: it
finds what a `package.` lookup would find in Carbon. So `X` is named
from C++ as `Carbon::X` still, and a lookup for `Carbon::Foo` fails,
even though `X`'s "true name" is now `Carbon::Foo::X`.
