Port Z Anti-Aliasing from BambuStudio-ZAA (https://github.com/adob/BambuStudio-ZAA)
to OrcaSlicer. ZAA eliminates stair-stepping on curved and sloped top surfaces
by raycasting each extrusion point against the original 3D mesh and micro-adjusting
Z height to follow the actual surface geometry.
Key changes:
- Add ContourZ.cpp raycasting algorithm (~330 lines)
- Extend geometry with 3D support (Point3, Line3, Polyline3, MultiPoint3)
- Template arc fitting for 2D/3D compatibility
- Change ExtrusionPath::polyline from Polyline to Polyline3
- Add 5 ZAA config options (zaa_enabled, zaa_min_z, etc.)
- Add posContouring pipeline step in PrintObject
- Update GCode writer for 3D coordinate output
- Add ZAA settings UI in Print Settings > Quality
- Add docs/ZAA.md with usage and implementation details
ZAA is opt-in and disabled by default. When disabled, the slicing pipeline
is unchanged.

* Fixed issue in a 32bit clipper, where IntersectPoint() checked for
the Y coordinate of the calculated intersection point for validity,
but the Y coordinate was already rounded to 32bits, thus an overflow
may have in rare cases masked invalidity of the result.

* Fix linux deps debug build
* Use the same DL_CACHE for release build when building debug version of deps on Linux.
This prevents downloading the same source packages twice, and avoid downloading again after deleting the build dir.
* Fix debug build
* Fix warnings "loop variable creates a copy from type" and "loop variable binds to a temporary constructed from type"
