Add width and height presentational hints for table-related elements (#33405)

Browse source 
We were only parsing the `width` attribute as a presentation hint for
`<table>`, `<td>` and `<th>`. This patch also handles `<colgroup>` and
`<col>`.

Also, we weren't parsing `height` at all, now we do it for `<table>`,
`<td>`, `<th>`, `<tr>`, `<tbody>`, `<thead>` and `<tfoot>`.

One test is now crashing, but this was an existing issue: #33423
