Feature: build-in DFTD3 parameters (#5378)

* Feature: build-in DFTD3 parameters with fall-back parameter search strategy * update * correct parameters * correct the annotation at the end of file dftd3.h * support libxc * add annotations * update alias: hse06 -> hse * [pre-commit.ci lite] apply automatic fixes * update the autoset strategy: if user defined, then use * fix compilation error * correct the unittest * xc with _v, _d3 should be carefully treated * give up the so-called fall-back strategy * correct a minor bug * disable the output * support the dft_functional value without the XC_ header * ouch... stupid mistake * Update doc * add more unittests * correct behavior on wb97 functional family according to advice --------- Co-authored-by: pre-commit-ci-lite[bot] <117423508+pre-commit-ci-lite[bot]@users.noreply.github.com>

 - **Type**: String
 - **Description**: Specifies the method used for Van der Waals (VdW) correction. Available options are:
   - `d2`: [Grimme's D2](https://onlinelibrary.wiley.com/doi/abs/10.1002/jcc.20495) dispersion correction method
-  - `d3_0`: [Grimme's DFT-D3(0)](https://aip.scitation.org/doi/10.1063/1.3382344) dispersion correction method
-  - `d3_bj`: [Grimme's DFTD3(BJ)](https://onlinelibrary.wiley.com/doi/abs/10.1002/jcc.21759) dispersion correction method
+  - `d3_0`: [Grimme's DFT-D3(0)](https://aip.scitation.org/doi/10.1063/1.3382344) dispersion correction method (zero-damping)
+  - `d3_bj`: [Grimme's DFTD3(BJ)](https://onlinelibrary.wiley.com/doi/abs/10.1002/jcc.21759) dispersion correction method (BJ-damping)
   - `none`: no vdW correction
 - **Default**: none
+- **Note**: ABACUS supports automatic setting on DFT-D3 parameters for common functionals after version 3.8.3 (and several develop versions earlier). To benefit from this feature, please specify the parameter `dft_functional` explicitly (for more details on this parameter, please see [dft_functional](#dft_functional)), otherwise the autoset procedure will crash with error message like `cannot find DFT-D3 parameter for XC(***)`. If not satisfied with those in-built parameters, any manually setting on `vdw_s6`, `vdw_s8`, `vdw_a1` and `vdw_a2` will overwrite. 
+- **Special**: There are special cases for functional family wB97 (Omega-B97): if want to use the functional wB97X-D3BJ, one needs to specify the `dft_functional` as `HYB_GGA_WB97X_V` and `vdw_method` as `d3_bj`. If want to use the functional wB97X-D3, specify `dft_functional` as `HYB_GGA_WB97X_D3` and `vdw_method` as `d3_0`.
 
 ### vdw_s6
 
 - **Type**: Real
 - **Availability**: `vdw_method` is set to `d2`, `d3_0`, or `d3_bj`
-- **Description**: This scale factor is used to optimize the interaction energy deviations in van der Waals (vdW) corrected calculations. The recommended values of this parameter are dependent on the chosen vdW correction method and the DFT functional being used. For DFT-D2, the recommended values are 0.75 (PBE), 1.2 (BLYP), 1.05 (B-P86), 1.0 (TPSS), and 1.05 (B3LYP). For DFT-D3, recommended values with different DFT functionals can be found on the [here](https://www.chemiebn.uni-bonn.de/pctc/mulliken-center/software/dft-d3/dft-d3). The default value of this parameter in ABACUS is set to be the recommended value for PBE.
