Introduce ITiledRenderable::getSheetGeometryData()

ITiledRenderable::getSheetGeometryData(bool bColumns, bool bRows,
bool bSizes, bool bHidden,
bool bFiltered, bool bGroups)

and implement it for the Calc derivation (ScModelObj).

The aim is to use it actively in LOOL instead of the interface:

ITiledRenderable::getRowColumnHeaders(const tools::Rectangle& /*rRectangle*/)

This is used by the LOOL to fetch the sheet geometry data for just the
current view-area in the clients, so LOOL queries this everytime some
client's view-area changes.

Like the existing interface, the new one will provide all 'kinds' of
sheet geometry info [col/row sizes(twips), hidden/filtered and
grouping]. But the difference is, it generates data for the whole sheet
(not view-area specific). So the method need not be queried every time
the view area changes in the LOOL clients, and more importantly it
enables the clients to locate any cell at any zoom level without any
further help from the core. This means core needn't send various
client(zoom) specific positioning messages in pixel aligned twips. It
just can send all positioning messages in print twips uniformly to all
clients.
