fix(printconfig): register enable_filament_dynamic_map and has_filament_switcher options
PR #13388 (X2D Support) added import/export for these options in
bbs_3mf.cpp but never registered them in PrintConfig.cpp. Loading any
.3mf containing these keys throws UnknownOptionException at
PartPlate.cpp:6153 when config->apply() looks up the missing definition.
