Add EntityType enum and support in StoredProcedureBuilder

Introduced the EntityType enum to represent target entities for stored procedure operations, along with XML documentation and mapping comments. Added EntityTypeExtensions with a ToDbString method for consistent DB string conversion. Updated StoredProcedureBuilder to support adding EntityType parameters, improving type safety and maintainability. Minor formatting and using directive adjustments included.
