Now that we never re-fulfill a promise image we no longer need to deinstantiate
promise image proxies. They now can use kSingleUse callback semantics.
This was the only usage of the kDeinstantiate lazy callback type so it is
removed. The DeinstantiateProxyTracker is also no longer required and is
removed.
The GrTexture idle callback mechanism now uses GrReleaseProcHelper, which has
been extended to support chaining multiple callbacks together and an abandon()
method that aborts calling the callback in the destructor. It has been renamed
GrRefCntedCallback to reflect its more general usage.
