pokemon: Convert to C from C++

Most of the application was written in straight C except for
`extern "C"` declarations and using the `_cpp` variant of
`with_view_model`. Removing/cleaning up these, plus rename, were
the only changes.

Additionally, compiled C code ends up being a couple hundred bytes
smaller, than the commit before this did.
