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.

At least one backend (i.e. --neon-backend, --cl-backend, --ref-backend) must be chosen.
This script must be executed from the same root directory in which setup-armnn.sh was executed from.
-This script will build using Arm NN and ACL repositories checked out in <ROOT_DIR>/source, downloaded using setup-armnn.sh.
+The first execution of this script will download the latest release branches of Arm NN and ACL, by default.
Alternatively, place custom/modified repositories named "armnn" and "acl" in <ROOT_DIR>/source.
+If providing custom repos, both Arm NN and ACL must be provided. The ACL repo will not be used if flags --neon-backend or --cl-backend are not selected.
By default, a tarball tar.gz archive of the Arm NN build will be created in the directory from which this script is called from.
