Reland "bench: Add PhoneHub assets to skottie-vs-png decode bench"

This is a reland of 0541a983eff91eeb0026662a96a6989ffe79b5b1

This time with Generic_Error.png instead of Generic Error.png, because
the space caused problems.

Original change's description:
> bench: Add PhoneHub assets to skottie-vs-png decode bench
>
> The skottie-vs-png decode bench is intended to facilitate comparison
> between Lottie and PNG, but such a comparison cannot really be made when
> the Lottie files are unrelated to the PNG files (Lottie files chosen to
> represent a range of vector graphic complexity, versus PNG files chosen
> to represent a range of image dimensions). This CL adds PhoneHub assets
> in PNG and Lottie, including various Lottie files created using
> different optimization strategies (see added code comments for details).
