bug#14197: 24.3.50; remove `kmacro-bind-to-key' prefix arg

[Drew Adams]

`kmacro-bind-to-key' has _ARG as a required argument.  Interactively
it is the numeric prefix argument.

Presumably this is an internal argument, based on the name.
But it is used nowhere in the code, AFAICT - not in
`kmacro-bind-to-key' or in any other code delivered with Emacs.
 
If it is really useless, as it seems, then remove it, including from
`interactive'.  (Or if it is really useful somehow, describe it in the doc
string.)

The ARGs aren't used, as far as I can see.  And since the doc strings
don't automatically say that _arg is unused, I've added this.

But perhaps the docstring stuff should say this automatically for _arg
parameters?
