Implement Snap packages

Note:

• Snap packages shall target the core18 base image, which is derived from the Ubuntu 18.04 LTS. This provides an Ubuntu 18.04-compatible library system on all Linux distros and effectively allows the packaged executables to run in a known environment (just like Poky in the meta-zephyr-sdk does).
• See https://snapcraft.io/docs/pre-built-apps for building Snap packages from the pre-built archives.
