  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
