qdoc: Improve format of obsolete members file

The link to the class reference page for the class that
contains the obsolete members is now embedded in the text
description of what the page contains. This change affects
both the obsolete members papge and the compatibility members
page. Without this change, the link to the class reference
page stands off on its own and makes it look like the class
itself is obsolete or maintained for compatibility with
previous versions. Since this is not the case, the link is
now embedded in the text description of the page.
