    doc/groff.texi: Drop stale ms-related node.
    
    Drop "Additional ms Macros" node.  It had three problems.
    
    * It didn't (comprehensively) document "groff ms macros not appearing in
      AT&T ms" as its subsubsection title claimed.  Instead these are
      documented where topically relevant.
    * `CW` is already documented in the "Typeface and decoration" node.
    * `IX`, a 4.2BSD ms extension, does not seem worth documenting (or even
      supporting, but that's a separate commit).  Tuthill's "A Revised
      Version of -ms" (1983) doesn't document it either, and I cannot find
      a 4.2BSD ms document that uses it.  Perhaps it was an experimental
      feature at the time.
    
    Removing the latter two leaves the node with no substance, so drop it.
