ENH: Improve CMP0012 doc and message formatting 

This fixes the CMP0012 description to have a one-line summary in the
'brief' section and the rest of the explanation in the 'full' section.
It makes the warning message shorter and improves formatting of the
policy documentation, especially in the HTML pages.  The convention is
already used by all other policies.
