PartDesign: PointPattern and CircularPattern behave weirdly #33143

Description

@UnKabaraQuiDev

Problem description

It looks like the Point/Circular patterns offset the transformations and duplicate the "original" feature

Workbench affected?

Part Design

Steps to reproduce

Use the new patterns
Examples:

more-pattersn.FCStd.zip

Expected behavior

The first transformation of the pattern should always be in the identity transformation. So that the first geometry instance doesn't even need to be applied because it already is present in the body's hierarchy.

Actual behavior

The Circular pattern keeps the original transformation but offsets all the others, they should probably be relative to the existing features
