Nanopb generates header files that need to be available before being
included. This isn't an issue for a target where the files were added
with zephyr_nanopb_sources. But if another target wants to include
these generated files we need a cmake dependency chain.
The nanopb_generated_headers custom target been added for this purpose.

instead of doing it ourselves.

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes

sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

Add the nanopb library and generator tools as a module.
Nanopb is a small code-size Protocol Buffers implementation in ansi C.
It is especially suitable for use in microcontrollers,
but fits any memory restricted system.
