Ⅰ. Describe what this PR did

Vector Mapping Core Features：

1. Field Mapping System : Enables mapping between standard field names and database-specific raw field names, allowing for flexible integration with different database schemas.
2. Index Configuration Management : Provides a structured way to define and retrieve vector index configurations, supporting various index types like HNSW, IVF, SCANN, and DISKANN.
3. Search Parameter Configuration : Allows customization of search parameters for different index types to optimize retrieval performance and accuracy.
4. Field Type Management : Specialized handling for different field types including ID fields, vector fields, metadata fields, content fields, and timestamps, each with specific configuration options.
5. Default Mapping Generation : Automatically creates sensible default mappings when not explicitly provided, simplifying the configuration process.
6. Field Property Customization : Supports configurable field properties such as maximum length and auto-ID generation for different field types, enhancing flexibility.
7. Required Field Validation : Ensures critical fields (id, content, vector) are properly defined in the mapping configuration, guaranteeing system functionality.
