Java: fix Javadoc roundtrip for multi-line HTML comments inside block tags

`visitComment` consumed `node.getBody().length()` characters of cursor and
emitted a single `Javadoc.Text` containing the entire body. For multi-line
HTML comments this dropped the leading-line `*` margins on print and left
the corresponding `LineBreak` markers stranded in the `lineBreaks` map,
where they leaked out as trailing `*` lines before `**/`.

Route `DCComment` through the same `visitText(body)` path that
`visitDocComment` already uses for top-level HTML comments, so the body's
newlines are processed and the margin `LineBreak`s are consumed.
