[Testing] Added windows/grpc_distribtests_cpp_dll (#34425)

Added a separate distribtests for gRPC C++ DLL build on Windows. This
DLL build is a community support so it should be independently run from
the existing Windows distribtests. Actual DLL test will be added.

+@rem NOTE(lidiz) We used to use "git submodule deinit", but it leaves an empty
+@rem folder for deinit-ed submodules, blocking the CMake download. For users
+@rem downloaded gRPC code as an archive, they won't have submodule residual
+@rem folders, like the following command trying to imitate.
+git submodule foreach bash -c "cd $toplevel; rm -rf $name"

+@rem NOTE(jtattermusch): The -DProtobuf_USE_STATIC_LIBS=ON is necessary on cmake3.16+
+@rem since by default "find_package(Protobuf ...)" uses the cmake's builtin
+@rem FindProtobuf.cmake module, which now requires the info whether protobuf
+@rem is to be linked statically.
