Boaz Brickner 68111a994c C++ Interop: Basic C++ record (class/struct/union) import support (#5156) ...

Focus: Calling static C++ function defined in C++ classes.

Limitations:
* Ignores visibility (public / protected / private).
* No support for: dynamic classes, member methods, data members,
declarations without definitions, importing inheritance.

Based on #5142.

C++ Interop Demo with a class:

```c++
// hello_world.h

namespace some_namespace {

class MyClass {
 public:
  static void hello_world();
};

}  // namespace some_namespace
```

```c++
// hello_world.cpp

#include "hello_world.h"

#include <cstdio>

namespace some_namespace {

void MyClass::hello_world() { printf("Hello World!\n"); }

}  // namespace some_namespace
```

```carbon
// main.carbon

library "Main";

import Cpp library "hello_world.h";

fn Run() -> i32 {
  Cpp.some_namespace.MyClass.hello_world();
  return 0;
}
```

```shell
$ clang -c hello_world.cpp
$ bazel-bin/toolchain/carbon compile main.carbon
$ bazel-bin/toolchain/carbon link hello_world.o main.o --output=demo
$ ./demo
Hello World!
```

Part of #5150.
