rustdoc: Use pulldown-cmark for Markdown HTML rendering

Instead of rendering all of the HTML in rustdoc this relies on
pulldown-cmark's `push_html` to do most of the work. A few iterator
adapters are used to make rustdoc specific modifications to the output.

This also fixes MarkdownHtml and link titles in plain_summary_line.
