nixos/manual: split manpages-combined from manual-combined

Browse Source 
once we generate the entire manual-combined.xml with a single
nixos-render-docs invocation we will no longer need any options xml
files. likewise we do not need the test options xml in the manpage
build. splitting manpages-combined from manual-combined also allows
these two to run in parallel, slightly improving build times.
