  Organize AST transforms per backend
  
  Most of the AST transforms are written as a workaround to an issue that
  affects a single backend.  This change identifies such transforms and
  organizes them by backend.  They are then only built if the respective
  backend is.
  
  Additionally, about half of the GL transforms are due to mac
  workarounds, including the large RewriteRowMajorMatrices transform.
  Mac-specific workarounds are additionally only built on said platform.
  
  This change reduces the ANGLE binary size:
  
  - 106KB in a Vulkan-only build on Linux
  - 27KB in a GL-only build on Android (60KB on Linux)

  // The SeparateArrayInitialization function splits each array initialization into a declaration and
  // an assignment.
  // Example:
  //     type[n] a = initializer;
  // will effectively become
  //     type[n] a;
  //     a = initializer;
  //
  // Note that if the array is declared as const, the initialization may still be split, making the
  // AST technically invalid. Because of that this transformation should only be used when subsequent
  // stages don't care about const qualifiers. However, the initialization will not be split if the
  // initializer can be written as a HLSL literal.
