Boaz Brickner 5705b94da8 Add PerformCallToCppFunction() which calls simplified version of PerformCppOverloadResolution() before calling PerformCallToFunction() (#6122)
Instead of calling `PerformCppOverloadResolution()` and use the complex
return value to call `PerformCallToFunction()`, we call
`PerformCallToCppFunction()` which will call both
`PerformCppOverloadResolution()` and `PerformCallToFunction()`.

Followup of #6112.
Part of #5995.

Boaz Brickner 88dac35ae8 Add support for C++ member operators (#6112)
Call `Sema::AddMemberOperatorCandidates()` to properly add candidates.
For C++ member operator calls, use the first arg as self.

C++ Interop Demo:

```c++
// my_number.h

class MyNumber {
 public:
  explicit MyNumber(int value) : value_(value) {}
  int value() const { return value_; }
  auto operator++() -> MyNumber;

 private:
  int value_;
};
```

```c++
// my_number.cpp

#include "my_number.h"

auto MyNumber::operator++() -> MyNumber {
  ++value_;
  return *this;;
}
```

```carbon
// main.carbon

library "Main";

import Core library "io";
import Cpp library "my_number.h";

fn Run() -> i32 {
  var num: Cpp.MyNumber = Cpp.MyNumber.MyNumber(14);
  Core.Print(num.value());
  ++num;
  Core.Print(num.value());
  return 0;
}
```

```shell
$ clang -c my_number.cpp
$ bazel-bin/toolchain/carbon compile main.carbon
$ bazel-bin/toolchain/carbon link my_number.o main.o --output=demo
$ ./demo
14

```
