tdf#122529 lok - table border position manipulation

This adds a new LOK callback (LOK_CALLBACK_TABLE_SELECTED) that
sends the border positions to the client when the user has the
cursor or slelection in a table.

In addition this adds a .uno:TableChangeCurrentBorderPosition
uno command, which implements changing a specific border in
the current table. Border can be either a column or a row border,
which is either at the first, middle or last position.
