feat(libslic3r): multi-nozzle slicing engine for H2C/A2L

Browse Source 
Port BambuStudio's dual-nozzle slicing core: H2C-era config keys, filament-to-nozzle grouping with per-layer dynamic regrouping, filament/nozzle/hotend gcode placeholder vocabulary, multi-nozzle wipe tower pre-heat/pre-cool, the two-pass pre-cooling injector, and corexy farthest-point timelapse.
