Modelling - Add option to not build history in BRepFill_PipeShell (#632)

- Adds `myIsBuildHistory` boolean member to `BRepFill_PipeShell` with default value `true`
- Implements getter/setter methods in both `BRepFill_PipeShell` and `BRepOffsetAPI_MakePipeShell` interfaces
- Conditionally calls `BuildHistory()` method based on the flag value
