Boaz Brickner 1d314c7c4d Import C++ constructors of class Type fn Type(...) -> Type (#5879 )

Only supports classes with a single (non copy non move) constructor
(without default values), until overloading is supported.

Based on #5878.

C++ Interop Demo:

```c++
// hello_world.h

#include <cstdio>

class C {
 public:
  C(int x, int y) : x_(x), y_(y) {}

  int x() const { return x_;}
  int y() const { return y_;}

 private:
  int x_;
  int y_;
};

void hello_world(C* _Nonnull c);
```

```c++
// hello_world.cpp

#include "hello_world.h"

#include <cstdio>

void hello_world(C* _Nonnull c) {
  printf("C.x = %d. C.y = %d\n", c->x(), c->y());
}
```

```carbon
// main.carbon

library "Main";

import Cpp library "hello_world.h";

fn Run() -> i32 {
  var c : Cpp.C = Cpp.C.C(1, 2);
  Cpp.hello_world(&c);
  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
C.x = 1. C.y = 2
```

Part of #5880.
