  [LifetimeSafety] Suggest/infer annotation in constructors (#191699)

This change improves the lifetime safety checker to detect when
constructor parameters escape to class fields and suggest appropriate
`[[clang::lifetimebound]]` annotations.

```cpp
struct A {
  View v;
  A(const MyObj& obj) : v(obj) {} // Now suggests [[clang::lifetimebound]]
};
```
