feat(trigger): enhance trigger subscription management and cache handling

- Added `name` parameter to `TriggerSubscriptionBuilderCreateApi` for better subscription identification.
- Implemented `delete_cache_for_subscription` function to clear cache associated with trigger subscriptions.
- Updated `WorkflowPluginTriggerService` to check for existing subscriptions before creating new plugin triggers, improving error handling.
- Refactored `TriggerProviderService` to utilize the new cache deletion method during provider deletion.

This improves the overall management of trigger subscriptions and enhances cache efficiency.
