Correctly pass screenshot fences to transaction callbacks
In some instances, a screenshot may be captured before a layer has a
release callback registered. This can happen when a new buffer has
not yet been transacted before a screenshot is captured. This causes the
screenshot fence to be dropped and the possibility of tearing when
capturing a screenshot while continuously rendering.
To resolve this, buffer screenshot fences into a list of future fences
when there is no callback registered, and merge those fences when
dispatching the release callback.
