    Implement deriving strategies
    
    Summary:
    Allows users to explicitly request which approach to `deriving` to use via
    keywords, e.g.,
    
    ```
    newtype Foo = Foo Bar
      deriving Eq
      deriving builtin Ord
      deriving newtype Show
    ```
    
    Fixes #10598.
    
    Test Plan: ./validate
