Don't import a C++ class definition until the class is required to be complete. (#5865)

When importing a class definition, ask Clang to complete it first. This
causes class template specializations to get instantiated as needed when
the type-checking of Carbon requires a C++ class to be complete. It also
allows Clang to implement things like modules-aware definition
visibility checking.

Don't reject importing a class with a virtual base if it's never
required to be complete. Instead, defer diagnosing until the definition
is required.

This also removes the recursion from `MapType`, as mapping a class type
no longer maps its definition.

In order to get diagnostics from instantiation failures, fix a bug that
caused any Clang diagnostics produced after the initial building of the
`ASTUnit` to get discarded. This exposed some duplicate diagnostic
issues in `ImportNameFromCpp` which are fixed here too.
