Subject: Add text wrapping to HTML output.

Previously the HTML writer was exceptional in not being
sensitive to the `--wrap` option.  With this change `--wrap`
now works for HTML. The default (as with other formats) is
automatic wrapping to 72 columns.

A new internal module, T.P.Writers.Blaze, exports `layoutMarkup`.
This converts a blaze Html structure into a doclayout Doc Text.

In addition, we now add a line break between an `img` tag
and the associated `figcaption`.

Note: Output is never wrapped in `writeHtmlStringForEPUB`.
This accords with previous behavior since previously the HTML
writer was insensitive to `--wrap` settings.  There's no real
need to wrap HTML inside a zipped container.

Note that the contents of script, textarea, and pre tags are
always laid out with the `flush` combinator, so that unwanted
spaces won't be introduced if these occur in an indented context
in a template.

Closes #7764.
