This also exposes the logic to export Carbon classes to C++ to apply during type mapping, which gives very slight support for passing Carbon types to C++ functions from Carbon, but not really enough to sensibly test yet.

Reverse interop support for type aliases. (#7043 )

Allow any type that has a mapping from Carbon to C++ to be exposed to
C++ via name lookup. This also exposes the logic to export Carbon
classes to C++ to apply during type mapping, which gives very slight
support for passing Carbon types to C++ functions from Carbon, but not
really enough to sensibly test yet.

Depends on #7042.

C++ Interop: Fix access calculation to handle private member of base classes correctly (#6238 )

Always take into account both the lookup access specifier and the
declaration. When set, lookup access specifier takes precedence. When
not set, we have two use cases:
1. This is not a record member, so no access is specified at all. Treat
this as public.
2. This is a record member of a base class. Treat this as private.

Also, deduplicate access mapping between import and overload resolution.
