Fix Surface slot caching
- Now that it's possible to resize a BufferQueue while buffers are
dequeued/acquired, it's no longer correct for Surface to clear its
cache when the BufferQueue is resized since it must keep at least
the currently dequeued buffers.
- Add an onSlotsFreed callback to IProducerListener so that producers
that wish to be notified about buffers being freed can do so. Note
that this isn't currently used in Surface.
- Review and fixup all the places where the producer/consumer
listeners for freed buffers should be called.
