Factor out arg_defs.rs for argument parsing related types

This change marks the first step in a restructuring of the argument
handling code, the ultimate goal of which is a separation of the type
definitions as used by structopt from the logic associated with it. This
change in particular introduces a new module, arg_defs, that contains
all those type definitions that previously resided in the args module.
