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.
