Zachary D. Rowitsch f642f4f17c Fix tables with captions not rendering and add caption layout support
Tables with <caption> elements were invisible because normalize_children
treated TableRowGroup/TableRow/TableCell as inline-level, causing them to
be wrapped in anonymous blocks when mixed with the caption (Block). The
table layout algorithm then couldn't find row groups among direct children.

Three fixes:
- Add table-internal types to is_block_level in normalize_children and
  determine_formatting_context so they aren't incorrectly wrapped
- Add table-internal types to render_non_inline_descendants in the
  display list builder so they render when nested in inline contexts
- Implement caption layout in calculate_table_layout: captions are laid
  out as blocks above the table rows, with rows offset accordingly
- Add text-align: center to caption in UA stylesheet per CSS spec
