Nicholas Bishop 2e21255855 Partial support for a generic class inheriting from a virtual C++ class (#8007) ...

This allows a generic class to inherit from a virtual C++ class as long
as the subclass doesn't override any methods. See
toolchain/lower/testdata/interop/cpp/class/import/inherit.carbon for a
working example.

The TODO in `CheckCompleteClassType` is now in
`CarbonExternalASTSource::CompleteType`, and only triggers if virtual
function thunks need to be defined.

A fix in `FileContext::BuildVtable` is also needed: when looking up the
clang decl associated with the vtable, if the class is generic then the
`ClassTemplateSpecializationDecl` associated with the specific is
needed. This required adding `ConstantStore::Get`, since only `const`
access is allowed during lowering.
