0028710: Implement 'BRepTools_History' history for algorithm 'ShapeUpgrade_UnifySameDomain'

'BRepTools_History' history was implemented for algorithm
'ShapeUpgrade_UnifySameDomain'.

The history of the changing of the initial shape was corrected to consider all
shapes created by the algorithm as modified shapes instead of generated ones.

The old history interface was replaced by the new one:
- to get the modified shapes use: History()->Modified();
- to check if the shapes has been deleted use: History()->IsRemoved().
