Extend enable/disable/set-state to all feature view types and REST/gRPC APIs #6429

Is your feature request related to a problem? Please describe.
The enable/disable/set-state commands for feature view state management (introduced in PR #6401) currently only exist under the feast feature-views CLI group and only support FeatureView and OnDemandFeatureView. There are no REST/gRPC API endpoints for these operations.

Describe the solution you'd like

• Add enable, disable, set-state CLI commands under on-demand-feature-views and stream-feature-views
• Update FeatureStore.enable_feature_view() / disable_feature_view() / set_feature_view_state() to handle StreamFeatureView
• Add REST and gRPC API endpoints for enable, disable, and set-state operations
• Add unit tests for new CLI commands and API endpoints
