Provide `factory-image.bin` with Meson

This automatically creates `build/artifacts/factory-image.bin` with the
Meson build system. The resulting file can simply be moved to the
virtual file system of the `nucleo_f767zi` board to flash bootloader and
application making the board ready for operation and remote updates.
