Add releaseMutexKey to ExternalImageAccessDescriptorDXGIKeyedMutex

This allows the client to specify a different release key for the keyed
mutex than the default of acquire key + 1. If the release key is the
sentinel value of UINT64_MAX, it's set to acquire key + 1. Once Chromium
transitions to always specifying the release key, it will be made a
required parameter and the default behavior will be removed.
