Move dependencies to args and commands modules into generated code

We are aiming to rid the arg_defs module of dependencies to the rest of
the crate in an attempt to make the file fully free standing. The last
remaining references into the crate are used to hook up the functionality
backing the respective commands. Luckily for us, this "gluing" of
functionality to types is really only required in the macro-generated
code (which we do not care about as part of this exercise) and so with
this change we remove the use declarations from the top of the file and
reference the respective functionality in an absolute manner instead.
