Allow to specify miter limit and arc tolerance for polypath offsetting
Enhances #28987. Closes #29886.
Recently I've been thinking that exposing miter limit and arc tolerance parameters for polygon/polyline inflating/deflating would be useful. I questioned whether it's reasonable to add those until this question/request was raised.
These parameters are added as default and reflect the defaults in ClipperOffset
which is used internally (the only parameters which were missing).
