refactor(IVolumeInput): remove useIndependentComponents property and …

…update related configurations

- Removed the useIndependentComponents property from IVolumeInput type definition and related configurations in various files.
- Updated the handling of blendMode and useIndependentComponents in addLabelmapToElement and addVolumesAsIndependentComponents functions to streamline volume input management.
- Cleaned up unnecessary comments and code related to independent components in SegmentationStateTypes.
