qdoc: Introduce codeprefix & codesuffix, re-introduce codeindent

In order to provide acceptable results for styling the documentation
for rendering using QTextBrowser (instead of a full browser engine),
QDoc needs flexibility in adjusting the generated HTML.

This commit introduces and documents codeprefix and codesuffix
variables for qdocconf, and re-introduces the once-removed
support for codeindent.

The default codeindent value is reset to 0. These changes have no
effect to the generated output unless the above variables are
defined.
