adl: Create Module Unit adl/oct

[flisboac]

This module unit includes all of its inner modules in its main .hpp file. Also, an additional .cfg.hpp should be responsible for all preprocessor verifications, if any.

All of this module's types (e.g. namespace-level typedefs, classes, enums, structs, unions) must be forward-declared in the module's .fwd.hpp header. Inner artifacts (e.g. module, component) are prohibited to forward-declare types anywhere else.
