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 模型的進入點，然後檢查目前如何處理執行階段註解和缺少的資料表。驗證對已棄用模型所要求的行為：現有資料表仍可使用，而不存在的資料表會被忽略，ORM 方法不執行任何操作或回傳空結果。
