ContextVK had been using a thread-local counter to assign the value returned by GetHash. But CommandPoolRecyclerVK was using these values as keys in a process-wide global map. If two engine instances using different task runner threads both created a ContextVK, then the thread-local counter could cause both contexts to share the same hash. So when CommandPoolRecyclerVK::DestroyThreadLocalPools destroys the pools associated with the first context's hash, it will also incorrectly destroy the second context's pools. Fixes https://github.com/flutter/flutter/issues/170141
