This PR applies several updates to C++ development within ssl-core and more, including:

• In order to enable the common/cpp library for embedded use:
  • Inside .cmake/essentials.cmake:
  • Makes all existing find_package s optional
  • Add nanopb package;
  • Add gRPC package (for high level code)
  • Update rules error and warning messages
  • Check if the dependencies of the rules exist, if not, it just issues a warning
  • Add robocin_cpp_nanopb_library rule
  • Add robocin_cpp_grpc_library rule
  • Add protocols relative path for all protobuf/nanopb/grpc library creation
  • Inside common/cpp:
  • Add version.h, similar to https://en.cppreference.com/w/cpp/header/version
  • Update libraries to use version.h #ifdef guards
  • Inside protocols:
  • Update protobuf libraries and create libraries for nanopb and grpc;
  • Let protocols CMake library be created as C library due embedded support
• Update existing GitHub actions/checkout from @ v3 to @ v4
• Add CIs:
  • Common C++ Library: Build, Run Tests and Install:
  • Builds the code for clang++, g++, and arm-none-eabi-g++
  • C/C++: clang-format
  • Gateway Augusto: Build and Run Tests:
  • Fix already-existing build errors
  • Remove common/cpp Dockerfile and the image directly
• Update containers/scripts installation directory
• Update CMake base version for containers that are using
• Add ssl-core-cpp-mbed-base.Dockerfile for embedded development
• Add nanopb.sh, arm-none-eabi-gcc.sh, mongocxx.sh and grpc.sh scripts

Open #116

Good job! Next time just try to reduce the PR size. 🚀

You're right, I'm sorry I'll avoid it again 😅
