Rethink constraints incorporation

Namely, remove incorporation “otherInsideMyConstraint” to eliminate constraint system redundancy and produce a potentially very large number of constructs. Instead, introduce not so “spreadable” incorporation during variable fixation (equality constraint with result type into other constraints). ^KT-41644 Fixed ^KT-42195 Fixed ^KT-42920 Fixed ^KT-42791 Fixed ^KT-41741 Fixed
