Cleanup code documentation

[MaciejKaszynski]

What

All documentation of the code shall use the same format

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

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

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