tdf#99396 SdrTableObj::EndTextEdit: restore cell format undo items

As seen by the user: after finishing the text edit of an Impress table
cell, the text changes are still on the undo stack, but the table ones
(like background color or vertical alignment) get lost.

This happens as SdrUndoManager::SetEndTextEditHdl() removes all undo
items from the stack which are created after the start of the text edit,
and creates a single item, but that doesn't include the table changes,
just the text ones.

Fix the problem by creating a copy of the CellUndo objects when it text
edit mode, and pushing them to the undo stack in
SdrTableObj::EndTextEdit(), which already writes the undo stack and runs
after the undo manager cleared the text edit items from the undo stack.
