PA_Line Calibration QOL improvements and tweaks (#14440)

* fix: constrain PA_Line calibration bounding box to model geometry

- PA_Line bounding box now uses actual model convex hull for X constraint instead of full printable area
- Skip EXCLUDE_OBJECT_DEFINE for PA_Line mode (single object, no exclusion needed)
- Add tool config files to .gitignore

* modified:   .gitignore

* fix: add gcode type annotations and fix box height in PA line calibration

- Label calibration segments with appropriate TYPE comments (Outer wall, Bottom surface, Top surface, Custom) for proper gcode processing
- Fix bounding box height calculation to account for z_offset
- Add LAYER_CHANGE and HEIGHT comments for multi-layer numbering display

* fix: lock PA_Line bounding box X to bed centre instead of model hull

* Added extra TYPE to ensure text/numbers/glyphs are labelled correctly

`  gcode << ";TYPE:Outer wall\n"; `

* Remove hardcoded Perl path in OpenSSL.cmake

Remove hardcoded Perl path for Windows configuration.

* Add cross compilation support for Windows in OpenSSL.cmake

* Remove unnecessary blank line in OpenSSL.cmake

* Set perl config command back to variable 

Accidentally uploaded version with hardcoded path for my local environment

* whitespace adjustment in previous

* removed personal .gitignore config

Remove specific files and directories from .gitignore.

* Fix box height parameter in DrawBoxOptArgs

Update DrawBoxOptArgs to use `m_height_layer` instead of `m_height_layer*2+z_offset`. This isn't a Z coordinate, it's a layer height

* Replace hardcoded extrusion type with call to `GCodeProcessor::reserved_tag` Etags

* Get pa_line bounding box from actual calibration variables

Updated calibration line bounding box calculation to use actual geometry for X bounds, using a fake call to generate the calibration pattern. 

This will accurately get the size of the calibration pattern, massively reducing wasted time from bed mesh probing.

* Implement print_extents method in CalibPressureAdvanceLine

Add print_extents method to calculate bounding box extents based on bed dimensions.

* Declare print_extents method in CalibPressureAdvanceLine

Added print_extents method to return X-bounds of the pattern.

* Fixed whitespace issues

* Adjust print_extents to account for delta printers

Check if the printer is delta layout and adjust bed dimensions if so.
Used code from `CalibPressureAdvanceLine::generate_test`

* Added semicolons to reserved tags

Didn't realise etags wouldn't add semicolon - added these

* only include number list in bounding box if number list is used

* avoid bounding box overflowing bed

* Tabs to spaces
