What this PR does / why we need it:

Adds a name field to TopologyConstraintGroupConfig in the scheduler API to make it easier to identify and manage topology constraint group configurations. The name is derived from the corresponding
PodCliqueScalingGroup (PCSG) name.

This change benefits:

• Easier identification when editing or adding topology constraint group configs
• Support for downstream schedulers (KAI) to reference and manage these configs by name

Special notes for your reviewer:

The name field is marked as required in the CRD. It will be automatically populated from the corresponding PCSG name by the operator.
