Re: Doc: NR add predefined paper sizes to appendix (issue 5783075)

My new ammended comment in the git format patch seems to not have been
included with git-cl

--snip--
Issue 2391

Copied predefined paper size entries from scm/paper.scm as a seperate
appendix entry in order to better document predefined paper sizes.

Also revamped section on Paper Sizes including better @cindex entries,
reworded explanation and examples including how to create a custom
paper size without the need to edit scm/paper.scm

Added note in scm/paper.scm to say that the appendix entry was not
autogenerated so that any new entries will not be forgotten to be added
in the appendix - until someone 'scripts' it.

If this is too large a patch now I can split it up.

It passes make and a full make doc.
