  Support substituting translated shaders.
  
  Add dumpTranslatedShaders and enableTranslatedShaderSubstitution
  frontend ANGLE features, which allow ANGLE developers to prototype
  optimizations and other transforms without fully implementing them in
  the shader translator.
  
  Tested on macOS with ANGLE's Metal backend, but should work with the
  other source-level translator backends.
  
  Add documentation for pre-existing substitution of shader sources, and
  of translated shaders added in this CL.
  
  Fixed: angleproject:8280
