PR for GSoC'21 project on Optimize OpenCV DNN for RISC-V. Related PR #20287.
This PR will further optimize DNN on the basis of #20287, especially when VLEN>128.
In #20287, we have used RVV Intrinsic to optimize the 4 kernel functions in DNN. However, if RVV vectors are 256-bit wide or more longer, then the current implementation will use only a part of them. This PR tries to adjustable to different vector sizes.
