CMake/Kconfig: CMake and Kconfig build integration

This commit allows for Zephyr modules to be natively integrated into
the build system with CMakeLists.txt and Kconfig files.

The sourcing of module files are done in following order:
- If <module>/zephyr/module.yml exists, use cmake and kconfig settings
  for sourcing of additional file
- Else if <module>/zephyr/CMakeLists.txt exists, source this file into
  CMake build tree and add <module>/zephyr/Kconfig as osource

If none of the above files are present, the project is considered to
not be a Zephyr module
