Work around un-safe downcast in PromiseLazyInstantiateCallback destructor after a context abandon

90% of this CL is just renaming. The only two substantive changes are:
   holding a GrTexture* (rather than a GrGpuResource*) in the GrTextureFreedMessage (this avoids the downcast)
   adding the abandoned() checks to the two GrContext::purgeUnlockedResources methods (this prevents accesses of the message queue)
