Added C++ wrappers - HDFFV-10149

Description:
    Added the following wrappers to class H5::Group:
    + H5Lcreate_soft:
        // Creates a soft link from link_name to target_name.
        void newLink(const char *target_name, const char *link_name,...)
        void newLink(const H5std_string& target_name,...)

    + H5Lcreate_hard:
        // Creates a hard link from new_name to curr_name.
        void newLink(const char *curr_name, const Group& new_loc,...)
        void newLink(const H5std_string& curr_name, const Group& new_loc,...)

        // Creates a hard link from new_name to curr_name in same location.
        void newLink(const char *curr_name, const hid_t same_loc,...)
        void newLink(const H5std_string& curr_name, const hid_t same_loc,...)

    + H5Lcopy:
        // Copy an object from a group of file to another.
        void copyLink(const char *src_name, const Group& dst,...)
        void copyLink(const H5std_string& src_name, const Group& dst,...)

        // Copy an object from a group of file to the same location.
        void copyLink(const char *src_name, const char *dst_name,...)
        void copyLink(const H5std_string& src_name,...)

    + H5Lmove:
        // Rename an object in a group or file to a new location.
        void moveLink(const char* src_name, const Group& dst,...)
        void moveLink(const H5std_string& src_name, const Group& dst,...)

        // Rename an object in a group or file to the same location.
        void moveLink(const char* src_name, const char* dst_name,...)
        void moveLink(const H5std_string& src_name,...)
Platforms tested:
    Linux/64 (jelly)
    Linux/ppc64 (ostrich)
