Enhanced support for the @Deprecated annotation.

**Is your feature request related to a problem? Please describe.**
Many applications evolve over time and this also means that Models are getting deprecated and aren't used anymore. By supporting this annotation we introduce a clear way for the engineer and ORM to handle this.

**Describe the solution you'd like**

- The auto migrator should ignore the annotated models **if the table doesn't exist already**.
- The ORM model should still be functional, if the table exists else the methods do nothing/return empty.

**Describe alternatives you've considered**
Check the annotation myself and don't make calls to the ORM methods.

**Additional Context**
The annotation has the RUNTIME RetentionPolicy and is therefore accessible at runtime.

首先定位 auto migrator 和 ORM 模型的入口点，然后检查当前如何处理运行时注解和缺失的表。验证对已弃用模型所要求的行为：现有表仍可使用，而不存在的表会被忽略，ORM 方法不执行任何操作或返回空结果。
