  Metal: Add fall back to from-source shader compilation
  
  We can't compile Metal shaders at build time without the chromium
  build directory and mac_sdk.gni. Add a graceful fallback to building
  the shaders from source at runtime in this case.
  
  Also detect the iOS simulator in gn and disable shader compilation.
  We don't have all the Mac SDK files needed to build shaders for this
  target yet.
  
  Bug: chromium:1385510
