Brian Salomon 876a017e53 Reland "Reintroduce deinstantiate lazy proxy types and use for promise images."
This is a reland of 8b40ac35b2

Original change's description:
> Reintroduce deinstantiate lazy proxy types and use for promise images.
> 
> This reverts a fraction of b2c5dae65d to
> restore the deinstantiate lazy proxy type, supporting implementation,
> and tests.
> 
> Use them for promise images to avoid thread safety issues for promise
> image resources. Makes promise image instantiation callbacks do a thread
> safe unref of their fulfilled GrTexture in GrResourceCache. The
> GrResourceCache mechanism for receiving unref messages is extended to
> allow multiple pending unrefs. All this is new.
