IVGCVSW-6777 Add Arm NN build-tool Dockerfile

* Adds Dockerfile associated with Arm NN build-tool scripts.
* The Dockerfile encapsulates the installation of system-wide
  packages (install-packages.sh), download/install of Arm NN
  dependencies (setup-armnn.sh) and the building of Arm NN
  and ACL (build-armnn.sh).
* A helper script for copying build contents from the built
  Docker image is provided for by docker-copy-to-host.sh.
* Modified existing scripts: moved the cloning of Arm NN and
  ACL from setup-armnn.sh to build-armnn.sh and decoupled
  setup-armnn.sh from scripts outside of build-tool directory
  e.g. armnn/scripts/get_tensorflow.sh.
* The build-armnn.sh script clones the latest release branches
  of Arm NN and ACL by default. Custom repos can be placed in
  the build-tool directory prior to 'docker build' and they
  will be used instead (advanced usage).
* Support added for Linux targets only, Android to be added
  in future work.
