doc: Ensure documentation lists output argument when it exists for functions in libinterp/
For new users of Octave it is best to show explicit calling forms
in the documentation and to show a return argument when it exists.

Add return arguments to @deftypefn macros where they were missing.
Attempt to use standard naming convention for return variables.
Occasionally improved the docstring itself by re-wording or adding code
examples.
