Richard Smith 9ae73d2847 Handle signature mismatch when a Carbon function overrides a C++ virtual function. (#7499) ...

When a Carbon virtual function overrides a C++ virtual function, we need
to export it with the C++ signature in order for it to work as an
override. Instead of mapping the C++ signature into Carbon and then back
again, use the original C++ signature from the base class as the
signature exported to C++.

Also add documentation explaining how we use thunks in C++ interop,
including in this new virtual function handling logic.
