robertphillips 8abb370aca Have GrSurfaceProxys and GrGpuResources draw from the same pool of unique ids
The idea here is that, for wrapped Proxy objects, we want the uniqueID to reflect that of the wrapped object. For this to work the IDs for the non-wrapped versions can't conflict with GrGpuResource's pool of IDs.

Split off of: https://codereview.chromium.org/2215323003/ (Start using RenderTargetProxy (omnibus))
