0027954: Create topology-preserving offset computation algorithm

Browse Source 
New topology-preserving offset algorithm has been added. It allows to construct offset shape of build solid.
test cases have been added.
Documentation has been updated to be up to date.

Minor corrections.
Grid is renamed for simplification purposes.
Old constructors are restored with Standard_DEPRECATED macros.
