* Added `duplicate plate` feature.
This the initial commit and this still needs work.

[#2025] Removed the `printf` statements.
* [#2025] Plate duplication is now fully implemented.
* [#2025] Updated icons for plate duplicate funcctionality.
* [#2025] Added toolbar icon fro "Duplicate Current Plate" action.

* [#2025] Addressed review comments.
* [#2025] Removed unused icons related to the previously introduced "Duplicate Plate" functionality.
* Fix for #3311:
The `config.filament_load_time.values` and `config.filament_unload_time.values` are completely ignored. This was working in PrusaSlicer and apparently BBS converted the `GCodeProcessor::TimeProcessor.filament_load_times` and `GCodeProcessor::TimeProcessor.filament_unload_times` from being `std::vector<float>` to just `float` and they were using the BBS specific and currently hidden `machine_load_filament_time` and `machine_unload_filament_time` config values. Reverted that change by copying those lines from PrusaSlicer.
* Fix for #3311:
Updated the previously fixed to code to keep compatibility with BBS printer .
* Fix for #3311:
Updated `GCodeProcessor::get_filament_unload_time()` to keep compatibility with BBS printers.
