For DDLs, Ganesh needs to know about External & Rectangle textures prior to instantiation (or PromiseImage fulfillment). These new flags allow the client to provide this information when the lazyProxy is created.
The new texture flags work analogously to the render target flags:
GrSurface and GrSurfaceProxy get a new set of accessors for the new flags
The new flags are set appropriately on a GrGLTexture when it is created
For wrapped texture proxies the flags are just copied off of the GrSurface
For lazy-proxies/promise-images the flags are computed up front and passed to the proxy
The GrSurfaceProxy/GrSurface flags equivalence is verified in GrSurfaceProxy::assign
