tdf#159483 sc HTML paste: handle data-sheets-formula attribute

When a formula cell gets copied from google docs, the value of the <td>
element only contains the formula result. This means once value cells
and formula cells gets copied together, the pasted formula cell won't
updated anymore when the input values change.

Turns out there is a data-sheets-formula attribute on <td> that contains
the formula, it seems it uses the R1C1 format.

Fix the problem by extending ScHTMLLayoutParser::TableDataOn() to parse
this attribute and set a formula on the target cell (rather than a
value) if the formula is available.

This required also extending ScEEImport a bit, since the HTML paste
builds on top of the RTF one in Calc.
