  Reland "Metal: translate IOSurface pbuffer's GL_RGB to RGBX/BGRX format."
  
  This is a reland of commit f102d75a39ec8980a617c179034c24f337b12d1c
  
  Nothing changed, it's just that the root cause was already fixed in
  https://chromium-review.googlesource.com/c/angle/angle/+/5937060.
  
  Original change's description:
  > 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.
