support for integration as a west module in zephyr (#395)

Integrate zenoh as a west module and enable adding zenoh as a library
using kconfig.

This will allows easier integration with zephyr by including in the west
manifest (west.yml), i.e.:

   remotes:
     - name: upstream
       url-base: https://github.com/zephyrproject-rtos

+      url-base: https://github.com/eclipse-zenoh

       revision: dec12fa3f0d790cafa8414a4c2930ea71ab72ffd

and then enabling the publication example with:

CONFIG_ZENOH_PICO=y
CONFIG_ZENOH_PICO_LINK_SERIAL=y
CONFIG_ZENOH_PICO_PUBLICATION=y

application can then be built with west:

west build -b reel_board zephyr/samples/publication
