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.

The Nanopb cmake locates the protoc executable, verify the result
instead of doing it ourselves.

Introduce a helper function zephyr_nanopb_sources to generate
source files and add these to a target.
