Cleanup code documentation

### What

All documentation of the code shall use the same format

```cpp
struct ProcessInfoData
{
int32_t status_ = -1; ///< Exit status for process
IComponent* component_ = nullptr; ///< Pointer to the termination callback associated with this item.
};
```

shall be changed to

```cpp
struct ProcessInfoData
{
/// @brief Exit status for process.
int32_t status_ = -1;

/// @brief Pointer to the termination callback associated with this item.
IComponent* component_ = nullptr;
};
```

### Acceptance Criteria (DoD)

### How
