Original change's description:
> [v8-platform] Store the platform in a unique_ptr
> 
> We want to change the signature of {CreateDefaultPlatform} in the V8
> API to return a unique_ptr instead of a raw pointer to indicate that the
> caller owns the platform. With this change we prepare pdfium for this
> change.
