Subject: [PATCH] examples/usercmodule: Add micropython.cmake to the C and CPP
 examples.

examples/usercmodule/micropython.cmake:

Root micropython.cmake file is responsible for including modules.

examples/usercmodule/cexample/micropython.cmake:
examples/usercmodule/cppexample/micropython.cmake:

Module micropython.cmake files define the target and link it to usermod.
