Seam: use scarf joint to minimize seam visiblity (#3839)

Browse source 
* Remember z of previous layer

* Support travel to middle of the layer z

* Support sloped extrusion

* Implement sloped seam

* Reduce extra movements

* Don't clip loop if sloped seam is enabled

* Fix wipe

* Ensure `slope_max_segment_length`

* Add options

* Limit slope length to perimeter length

* Fix slope segmentation

* Rename the option to scarf joint seam

* Don't modify the slope option when turning on spiral vase

* Add a few suggestions when turnning on scarf joint

* Add option to add scarf joint to inner walls

* Apply seam gap at the end of the slope

* Add option to explicitly use the entire loop as scarf length

* Fix layer number

* Increase default scarf length to 20mm

* Better way of storing the global scarf state

* Better vase mode layer height recognition

* Move id should exclude seams

* Fix slope height with independent support layer height

* Fix linux build

* Allow controlling the scarf with modifier

* Scarf start height default to 0

* Allow enable scarf seam on contour only

* Fix type error

* Move the creation of sloped loop into ExtrusionEntity.cpp

* Fix error "vector too long"

* Detect seams properly

* The correct way of calculating the rate limit

* The correct way of calculating the rate limit

(cherry picked from commit 05961f7c98)

* Add pressure equalizer in print by object mode

* Remove the settings recommendation as it varies a lot depends on printer & filament

* Add a beta suffix
