CI: Add automated container build

This commit adds a Container which holds the CCS and SDK so they can be
used to build the various firmwares.

The pipeline can be later expanded to also actually build the
firmware(s).

+## Docker build environment
+
+This repo includes a Container file, to help with setting up a build environment without the need to download and install things manually. [Docker](https://docker.com) or [Podman](https://podman.io) can be used. The following example uses docker.
+
+1. This step builds the container locally. This step may be skipped if using a [released container](https://github.com/Koenkk/pkgs/container/Z-Stack-firmware) from this repository instead.
+```console
+$ docker build \
+    --file '../../Containerfile' \
+    --rm \
+    --tag 'z-stack:dev' \
+    '../../'
+```
+
+> __Note:__ The above instruction assumes we are in the coordinator/Z-Stack_3.x.0 directory, which is why we refer to the repo root. Replace `../../` with `./` if run from the root.
+
+> __:Warning:__ The build of the container will download CCS. While docker keeps a cached copy on subsequent builds, this download can take a while and is not immediately obvious it is happening.
+
+1. Enter the container so that the firmware can be built.
+```console
+$ docker run \
+    --interactive \
+    --rm \
+    --tty \
+    --volume './:/src' \
+    --volume '../../simplelink_f2_examples_sdk:/sdk' \
+    --volume './workspace:/build/workspace' \
+    --workdir '/build/workspace' \
+    'z-stack:dev' \
+    '/bin/bash'
+```
+
+> *Warning:* It is required that this repository has been cloned recursively and the Simple Link being volume mounted to `/sdk` as described above. Also the various `znp.syscfg` files are volume mounted to `/src`. This last path is not per-say needed and later where `znp.syscfg` gets copied could also be copied directly from the host. This is just a preference for the most part.
+
+> __Note:__ The local directory `./workspace` is volume-mounted into the containers `/build/workspace` directory to be able to keep files from the container, but can be freely removed when done.
+
+Within the container, we now follow similar steps as above, however the SDK needs be compiled and registered first.
+
+1. First, the SDK libraries will need to be compiled.
+`#  make --directory='/sdk/cc13xx_cc26xx_sdk' --jobs=$(($(nproc) - 1)) build-ticlang`
+
+1. Next, register the SDK to CCS
+`# eclipse -noSplash -application com.ti.common.core.initialize -ccs.productDiscoveryPath '/sdk/cc13xx_cc26xx_sdk/'`
+
+> *TIP:* Entering the container is convenient, but not required. Instead of using `/bin/bash` to enter a shell, commands can be put there instead as well. Even adding the word `eclipse` is not even needed in that case. E.g. `docker run ... --help` will already work. The SDK is registered in this case automatically as well. An alias could be set to the long docker comamnd, and thus `zstack --help` could be even used (assuming zstack is the name of the alias). This can be convenient when developing on the stack, and wanting to rebuild based on the change.
+
+### Launching eclipse in the container
+To launch eclipse in the container to test/check things out. This does require a X11 compatible host.
+ ```
+--env DISPLAY="${DISPLAY}" --volume '/tmp/.X11-unix' --network='host'
+```
+> __Note:__ The network mapping is required for local X11 forwarding to work due to the `DISPLAY` variable assuming `localhost`.
+
+Within the container, eclipse does require `libswt-gtk-4-java epiphany-browser` installed (ccs/eclipse does come with chromium, but epiphany is an easy way to fulfill its missing dependencies).
+
+Almost certainly some additional security mechanisms need to be bypassed, where a quick (and dangerous) hack is to `xhost +` on the host before launching the container.
+
+Finally start `eclipse -data '/build/workspace'` from within the container and it will then pop up a UI window on the host.
+
+> __Note:__ Optionally, a VNC in docker solution or X11 forwarding over ssh can also be used, but that is out of scope for here.
