Richard Smith d08805f1a6 Fix Carbon:: name leakage across files. (#7973) ...

Split the `Carbon::` namespace into one semantic namespace tree, plus
one separate lookup-only namespace tree per Carbon file. Use the
semantic namespaces as the parents of entities, but use the lookup-only
namespaces when C++ name lookup names a Carbon namespace, in order to
use a different C++ name lookup table in each Carbon file.
