ChatON+: Cleanup integration with CMake

Rename chaton-meta hpp to cpp and include this cpp file which brings
in the compile time built-in global chaton configurable template data
into the common library, and avoid the nop hpp file references.

Update chaton.hpp to not include the meta-cpp, instead just make a
reference to the global ChatTemplates instance, so that the hpp can
be used as a header file proper.

Avoid pragma once in the chaton-meta.cpp, including the script, which
helps create it.
