Fix Cmake build environment and harden Warnings

-Remove unused sweetcomb CmakeList.txt Warnings
-Add more Warnings to plugins, scvpp and gNMI Cmake projects
-Remove unused/useless Cmake options in CmakeList files & add comments
-Improve gNMI CMakeList.txt and make it independant of a gRPC cmake build for
later package integration.
-Add FindGRPC.cmake
-Remove the use of CXX17 variant and use a dedicated Cmake module for
gRPC
