Update build system and docs to new minimum cugraph-0.20 requirements (…

…#1552) Close #1528 Following cuDF (rapidsai/cudf#7780) cugraph-0.20 increase the minimum requirements in the following way: GCC version 9.3+ is required CUDA and C++ code now is compiled with -std=c++17 We require CUDA Toolkit version 11.0 or greater This updates the build-system and the README with these new requirements Authors: - Seunghwa Kang (https://github.com/seunghwak) Approvers: - Chuck Hastings (https://github.com/ChuckHastings) - AJ Schmidt (https://github.com/ajschmidt8) - Brad Rees (https://github.com/BradReesWork) URL: #1552
