Add CallAction to allow deferring calls (#7682)

Browse Source 
Calls with template callee or args can now be deferred via an
InstAction. This allows code like this to check:

```carbon
import Cpp inline '''
template<typename T>
struct C {};
''';

fn F(generic T: type) {
  let unused c: Cpp.C(T) = Cpp.C(T).C();
}
```
