Typst writer: support Typst 0.11 table features. (#9593)

* Typst writer: support Typst 0.11 table features.

- colspans
- rowspans
- cell alignment overrides
- relative column widths
- header and footer
- multiple table bodies with intermediate headers

Row heads are not yet supported.

The default typst template has been modified so that tables
don't have lines by default. As is standard with pandoc, we only
add a line under a header or over a footer. However, a different
default stroke pattern can easily be added in a template.

Closes #9588.
