Adds .aliases = { "wall_filament", "wall_filament_id", "outer_wall_filament",
"perimeter_extruder" } to outer_wall_filament_id and .aliases = { "inner_wall_filament" }
to inner_wall_filament_id in PrintConfig.cpp so that old .3mf files using these legacy
keys do not throw UnknownOptionException on load.

Also corrects verify_build.sh CHECKS to search for "tray_sub_brands" (the actual binary
string) instead of the stale "filament_sub_brands".
