This PR adds the same functionality as provided by Part Extrude.
The used code parts are sorted out to a new helper function that is used by Part and PartDesign.
Introduce an enum to verify the axis depending on the used context.
* For helix no restriction is needed
* For Pad/Pocket the axis must not be parallel with the sketch plane
* For Revolve/Groove the axis must not be perpendicular with the sketch plane
- let FeatureExtrude set the right direction
- use the UI as once intended: custom vector values are always taken as they are, so reversing a custom direction will not lead to a negation of the custom vector in the UI. The logic is: "take the vector as it is, and when Reversed is on, negate it additionally"
