tdf#84394: xls load: delay cell-anchoring of object groups

When cell-anchored object groups are loaded, their anchoring must be
delayed until all nested objects have been loaded, lest the invalid
rectangle dimensions lead to incorrect positioning of the object.

To achieve this, we keep track of the DffObjectData of the pending
group, and move the anchoring to a FinalizeObj() method.

Since DffObjectData has a const reference to a DffRecordHeader (which we
need when setting the object anchoring) whose scope has closed by the
time we call FinalizeObj() on the parent object, the stack of pending
DffObjectData has references to clones of the original DffRecordHeader
held in shared pointers. (This is to minimize the invasiveness of this
patch wrt the Import* API.)
