Path: Integrate 4th-axis feature to PathPocketShape and 3D Surface ops (#2114)

* PathSurface: Add StepDown support

Add StepDown support for PathSurface operation.
A low-level optimization algorithm is included.

* Update PageOpSurfaceEdit.ui

* PathSurface: Activate CompletionMode input

Update code to use CompletionMode selection from user.

* PathSurfaceGui: Add Completion Mode selection box

Add Completion Mode selection box for user input.

* PathSurface: Use depth_params() for step control

Implemented PathUtils.depth_params() for control of step downs to maintain consistency throughout PathWB.
Suggested by Sliptonic.

* PathSurface: Improve stability - Rev3

Organized code better, improved path optimization algorithm

* PathSurface: Add XY rotational surfacing

Add options to perform 3D surfacing by rotating object around X or Y axis.

* PathSurface: update setup function

Add properties to setup function

* PathSurface: Remove extraneous code

removed commented lines that consume processing time

* PathSurface: Correct nxt.z point assignment

Corrected error in nxt.z value assignment. Was assigning value to pnt.z instead of nxt.z

* PathSurface: Update 4th axis operation

Provided both parallel and perpendicular to axis  scans when performing rotational operation.

* PathSurface: Corrected Y-axis rotation to gcode

Inverted Y-axis scan values in gcode to produce correct result

* PathSurface: Adjust gcode feed rates

Adjust feed rates for axial rotations

* PathSurface: Implement waterline alternative

Used OCL dropcutter scan as data base for python algorithm to extract a waterline.  Waterline also incorporates step down feature.

* PathSurface: Update to 3m-Usable

stability improvements
fixed step on multi-pass 4th axis scans
initiate code to accommodate cut modes: zigzag, line
initiate code to accommodate offset cutter on 4th axis scans to simulate a tilted cutter for ball end mills

* PathSurface: Update 3m-Usable_r1

change instantiated static class attributes from value None, to 0.0

* PathSurface: Revert to 3i-Usable_r1

Further testing needed for 3m-Usable release

* PathSurface: Update to Rev. 3s Usable

fixed step over in rotational scans
start/stop indexes
tilt cutter adaptation for ball end mill
cut pattern: zigzag, line partially implemented
ignore waste option initiated for planar scans
cut mode partially implemented: conventional & climb

* PathSurface: Update to Rev. 3t Usable

Corrected rotational errors
corrected cutter tilt rotation
added "ignore waste" feature for planar surface operation

* Implement 4th-axis feature

Implement 4th-axis feature:
add gcode commands for rotation
re-compute operation heights, to consider rotation radii

* Deleted reference to undeclared variable

* Added missing class attributes/variables

* Added missing class variables/attributes

* Relocate class variables to higher class

* Remove references to undeclared variables

relocated class variables here
delete references to undeclared variables

* Correct rotation direction for normal-to-Y faces

* Remove X oriented 180 degree rotation adjustment

Probable error in FreeCAD gcode renderer, producing incorrect B axis rotation

* Update 4th-axis integration

Address FC error with B axis rotation rendering: user input to override error for visual alignment with model.
Correct pocket depths with Final Depth input enforced.
Add Reverse Direction flag input for reversing direction of pocket: necessary in some use cases.
NOTE: 4th-axis throws errors with Extension Corners feature.  EC feature needs 4th-axis rotation integration when calculating extensions for a particular part feature/face.
General testing needed.

# SCRIPT NOTES:
# - Need test models for testing vertical faces scenarios. Currently, I think they will fail with rotation.
# - Need to group VERTICAL faces per axis_angle tag just like horizontal faces.
# Then, need to run each grouping through
# PathGeom.combineConnectedShapes(vertical) algorithm grouping
# - Need to add face boundbox analysis code to vertical axis_angle
# section to identify highest zMax for all faces included in group
# - Need to implement judgeStartDepth() within rotational depth calculations
# - FUTURE: Re-iterate PathAreaOp.py need to relocate rotational settings
# to Job setup, under Machine settings tab
