* Improve multiline fill offset and polyline closure

Changed offset type from jtRound to jtMiter in multiline_fill for better geometry. Updated polyline conversion to require at least 3 points and ensured polylines are closed if not already. Updated FillGyroid, FillTpmsD, and FillTpmsFK to pass the 'close' argument to multiline_fill.

Improved Multiline Function

This ensures `multiline_fill()` will correctly generate multiline infill with
closed loop polylines if the input infill line is a closedloop polyline. This
ensures that the multiline infill doesn't have little gaps or overlaps at the
"closed point" of the original infill line.

This changes how the tangent is calculated for the first and last points in a
polyline if the first and last points are the same, making it a closed loop.
Instead of just using the first or last line segment, it uses the line segment
between the points before the last point and after the first point, the same
way that all the other poly-line mid points are handled.

It also uses eigen vector operations to calculate the points instead of
explicitly calculating the x and y values. This is probably faster, and if not
then it is at least more concise.

* Switch multiline offset logic to Clipper2

Replaces Clipper-based multiline offset logic in FillBase.cpp with Clipper2, using InflatePaths and Union for offsetting and merging. Adds new conversion utilities in Clipper2Utils for handling Paths64 to Polygons/Polylines and updates headers accordingly.

* Refactor multiline_fill to always use Clipper2 logic

Removed the 'use_clipper' parameter from multiline_fill and updated all callers to use the new signature. The function now consistently applies Clipper2-based offset logic for multiline infill, simplifying the code and ensuring uniform behavior across fill patterns.

* Change offset join type to Round in multiline_fill

Replaces the Miter join type with Round in the InflatePaths call within multiline_fill. For smotther print travels.

* Increase max infill multiline to 10

Raised the maximum allowed value for the 'Fill Multiline' infill parameter from 5 to 10 to support more lines in infill patterns.

* Refactor multiline_fill to optimize offset logic

Replaces manual conversion of polylines to Clipper2 paths with Slic3rPolylines_to_Paths64 and filters short paths using std::remove_if. Uses ClipperOffset for path inflation and streamlines merging and conversion to polylines, improving performance and code clarity.

* half iteration because is bucle

* Funciona 1

Refactored the multiline_fill function to streamline the insertion of center lines by directly checking for odd line counts and removing redundant logic. This improves code clarity and reduces unnecessary checks.

* Refactor multiline_fill for improved offset logic

Reworked the multiline_fill function to simplify and clarify the logic for generating multiple offset lines. The new implementation computes offsets more explicitly for odd and even cases, creates a fresh ClipperOffset for each band, and improves conversion between Clipper2 paths and polylines. This enhances maintainability and correctness of the multiline fill generation.

* Refactor multiline_fill to clean polylines and reuse offsetter

Invalid polylines with less than two points are now removed before processing. The ClipperOffset object is created once and reused for each offset, improving efficiency and code clarity.

* Optimize Filltrapezoidal

Refactored the trapezoidal fill pattern generation to precompute base row templates and reuse them with vertical translation, reducing redundant computations and improving code clarity. This change enhances performance and maintainability by avoiding repeated construction of row patterns within loops.

* Replace push_back with emplace_back for Polyline points

Updated Polyline point insertion from push_back to emplace_back for efficiency and clarity. Also refactored row copying logic to avoid in-place modification, improving code readability and safety.
