Original change's description:
> Allow building with Wuffs v0.3, not just v0.2
> 
> This is step 1 of a multi-step, multi-repository transition:
> 
> 1. Let Skia work with either Wuffs v0.3 or v0.2. This repository
>    defaults to v0.3 but other repositories' defaults remain at v0.2.
> 2. Update users' Skia version (automatic if they update regularly).
> 3. Update users' Wuffs version and opt them in to Skia-uses-Wuffs-v0.3.
> 4. Flip Skia choosing Wuffs version 0.3 from opt-in to opt-out.
> 5. Remove the option for Skia to work wih Wuffs v0.2.
