  Translator: Reorganize files
  
  This change makes the translator files more organized by:
  
  - Grouping files that are specific to a certain output under their own
    directory,
  - Moving transformations under tree_ops
  - Removing Direct from metal translation now that that SPIR-V Cross path
    is removed

  //    - Dependency inject the internal pipeline struct to all functions that access variables from
  //      the struct.
  //    - A new external pipeline struct is created if needed for impedance reasons. Otherwise the
  //      external and internal pipeline structs are the same.
  //    - Add `main` parameter or return value for the external pipeline struct as needed.
  //    - Inside `main`, map the external struct to the internal struct if they differ and is provided
  //      as a parameter to `main`.
  //    - Inside `main`, map the internal struct to the external struct if they differ and is returned
  //      from `main`.
