  Metal: translate IOSurface pbuffer's GL_RGB to RGBX/BGRX format.
  
  Currently when IOSurface is bound to a pbuffer with GL_RGB internal
  format, we asign angle format=B8G8R8A8_UNORM/R8G8B8A8_UNORM to it.
  And then disable alpha write to the respective MTLTexture.
  
  However, when an implicit MSAA texture is created for the above
  pbuffer, it will be assigned B8G8R8A8_UNORM/R8G8B8A8_UNORM angle format
  but has no knowledge about alpha write disable. Consequently, when a
  render pass uses this implicit MSAA texture, its alpha channel won't be
  cleared properly and would contain garbage values.
  
  In order to avoid the above bug, we should use
  B8G8R8X8_UNORM/R8G8B8X8_UNORM angle format for the IOSurface pbuffer.
  
  This will fix the render corruptions found in chromium:358957665.
