  Choose direct-to-Metal translator through a feature.
  
  Define directMetalGeneration in FeaturesMtl.h. If
  ANGLE_ENABLE_METAL_SPIRV is defined to 1 (still the default),
  directMetalGeneration defaults to false. It can be overridden via the
  standard ANGLE mechanism:
    ANGLE_FEATURE_OVERRIDES_ENABLED=directMetalGeneration
  
  It can also be overridden by instantiating angle_end2end_tests with
  the directives:
    WithDirectMetalGeneration(ES2_METAL())
    WithDirectMetalGeneration(ES3_METAL())
  
  These directives aren't working properly yet though. The
  direct-to-Metal compiler is instantiated, but the _DirectMetalGen
  versions of the tests fail. They pass when switching the Metal
  backend's default behavior using the above environment variable. This
  will be debugged in follow-on CLs.
