bIsHeightmapMerge

COMMENT [jonathan.bard] : purposefully don't use ELandscapeToolTargetType here as [ELandscapeToolTargetType::Weightmap](API\Runtime\Landscape\ELandscapeToolTargetType) and [ELandscapeToolTargetType::Visibility](API\Runtime\Landscape\ELandscapeToolTargetType) have to be processed together (because of weightmap packing, which means a visibility weightmap could be another channel of a texture which contains weightmap up to 3 other weightmaps, so we have to resolve the 4 channels altogether).
