Merge website and CMake to Meson transition

Building a website to structure and deploy the artifacts was planned and
requires a well set-up build system to handle all the file paths targets
and dependencies.

Since multiple CMake Zephyr builds are required for the application
firmware, bootloader firmware and the native_sim application firmware
simulation CMake external project was used.

Since this generates a build tree with a confusing structure Meson was
evaluated.

Finally the Meson build system was a good fit as top-level build system
and allows external projects as an experimental feature if they can
configure a Make-based build system which is given for Zephyr.

 iot-contact is an IoT device to check if doors and windows are closed or open.
 Furthermore roller shutter motors should be controlled.
 
-Currently two boards are supported:
-
-- `native_sim/native/64` without bootloader
-- `nucleo_f767zi` with bootloader
-
 ## Usage
 
-To build the device repository a firmware signing key is required. It is
-generated with the `imgtool.py`.
-
-```
-mkdir ~/mcuboot
-./imgtool.py keygen --key ~/mcuboot/key.pem --type ed25519
-```
-
-The content of this repository can be build with CMake and Ninja. The
-application firmware will be built for the simulation board to easily use it
-without special hardware.
-
-The bootloader is built for `nucleo_f767zi` since the simulation board is
-currently not supported.
+The source code can be retrieved with `git`.
 
 ```
-cmake -Bbuild -GNinja
-ninja -C build
+git clone https://cgit.xengineering.eu/iot-contact
+cd iot-contact
+git submodule update --init
 ```
 
-A custom key location can be set by providing `-DKEY=/path/to/key` to the CMake
-call.
-
-To run the simulated firmware a virtual network interface `zeth` and a router
-advertisement daemon have to be provided with an embedded script. Root rights
-are required for that (prefix e.g. with `sudo`).
+To sign the application firmware and thus to build the project a cryptographic
+signing key is required. It can be generated with `imgtool.py`.
 
 ```
-./fw/simulate-network.sh
+mkdir ~/mcuboot
+./imgtool.py keygen --key ~/mcuboot/key.pem --type ed25519
 ```
 
-With the firmware built and the network being prepared the simulated firmware
-can be run.
+The project is built with the Meson build system.
 
 ```
-./build/fw/app/zephyr/zephyr.exe
+meson setup build
+meson compile -C build
+meson install -C build --destdir artifacts
 ```
 
-To build the firmware in a clean `nucleo` build folder, flash it and open a
-serial interface another script can be used for convenience.
+The resulting artifacts can be listed with `tree`.
 
 ```
-./fw/nucleo.sh
+tree build/artifacts
 ```
 
-Next to the firmware artifacts the exported files related to the printed
-circuit board (PCB) can be found in the build folder.
+These artifacts are organized as static website. It can be opened with Firefox.
 
 ```
-tree build/pcb
+find build/artifacts -name 'index.html' -exec firefox {} \;
 ```
