xmloff: import and export for the chart data table

This change adds import and export code for the the chart's data
table properties to the ODF format for chart documents. The data
table properties are exported to a new element "data-table", which
then references a auto style with all the properties of a data
table + new data table specific properties: HBorder, VBorder,
Outline, Keys which are mapped to "show-horizontal-border",
"show-vertical-border", "show-outline" and "show-keys" chart
attributes.

Also adds a test for the import and export:
imports xlsx -> exports to ods -> imports ods
