More fine grained build configuration for CLI topols (#921)

Grant more fine grained control of how the CLI tools are built, e.g. if only benchmarks are required, don't build the validation tools and vice versa. Also allows to build the CLI validation tools without building unit and integration CI tests.
This will be helpful in order to set up the benchmarks across different hardware platforms with minimal dependencies.
