CLP-11811 copy cell properties from table styles

[jurisdatum]

Sometimes there is cell formatting associated with a table style. In the XML, we might see CSS in the <presentation> block that looks like this:

.TableGrid td { border: 0.5pt solid; }

and then some XML in the body that looks like this:

<table class="TableGrid">
   <tr>
      <td>...</td>
   </tr>
</table>

With the included fix, these cell properties will be copied into the style attribute of the HTML like this:

<table>
   <tr>
      <td style="border: 0.5pt solid">...</td>
   </tr>
</table>

We already do something similar with inline styling contained in a paragraph style. This fix just extends it to table styles.
This fix is needed for [2024] UKFTT 564 (TC). See Jira issue CLP-11811
