Auto-delete consumed roughness source after metallic-smoothness repack

Browse Source 
PolyHavenMaterialBuilder now removes the separate roughness map (asset +
meta) once its data has been packed into the generated
_metallic_smoothness.png; skipped when the repack fails or roughness came
from the ARM texture.
