Subject: [PATCH 3/4] cmake: Add an ordering dep between HTML & man Sphinx
 targets

Add a dependency between HTML & manpage Sphinx targets to prevent two
instances of Sphinx from running in parallel, and therefore solves race
conditions reusing the same doctree directory.

Fixes: https://llvm.org/bugs/show_bug.cgi?id=23781
