Add extrusion role change G-code in Process and Filament (#11784)

Browse Source 
* Add extrusion role change G-code options

Introduces new G-code options for handling extrusion role changes at the process and filament levels. Updates configuration, GUI, and GCode logic to support 'process_change_extrusion_role_gcode' and 'filament_change_extrusion_role_gcode', allowing custom G-code insertion when the extrusion role changes.

* Optimize extrusion role-change gcode handling

Cache gcode template strings and current filament id, and guard creation of DynamicConfig/placeholder processing behind a check that at least one role-change gcode is non-empty. This avoids redundant config lookups and DynamicConfig/placeholder parsing when no custom role-change gcode is defined, improving clarity and performance without changing behavior.
