  (Reland) [Metal] Disable ANGLE's Metal backend on older GPUs.
  
  Disable creation of EGL_PLATFORM_ANGLE_TYPE_METAL_ANGLE displays on:
    iOS: MTLGPUFamilyApple2 and older (A8 and older GPUs)
    macOS and Mac Catalyst: MTLGPUFamilyMac1 and older
  
  This is a partial integration of this recent WebKit fix:
  https://bugs.webkit.org/show_bug.cgi?id=242764
  
  Refactored to eliminate duplicate copies of this code between libANGLE
  and the test suites.
  
  Changes since initial landing:
  
  - Explicitly link the angle_common static library against
    Metal.framework for the definition of MTLCreateSystemDefaultDevice,
    which was missing on the iOS Simulator.
  
  Fixed: angleproject:7514
