Drop all documentation formatters except Usage

We now need only the Usage formatter to support command-line options
that print basic usage, and the supporting indented=>preformatted markup
processor to support CMake message formatting.  Drop all other
documentation formatters and move the remaining code up into the top
cmDocumentationFormatter class.
