Added new C++ wrappers - HDFFV-10622

Description:
    Added wrappers for H5Pset/get_create_intermediate_group:
        // Specifies in property list whether to create missing
        // intermediate groups
        void setCreateIntermediateGroup(bool crt_intmd_group) const;

        // Determines whether property is set to enable creating missing
        // intermediate groups
        bool getCreateIntermediateGroup() const;
Platforms tested:
    Linux/64 (jelly)
    Linux/64 (platypus)
    Darwin (osx1011test)
