GraphicBuffer: add optional DetachedBufferHandle
Stores a BufferHub handle that can be used to reattach this
GraphicBuffer back into a BufferHub producer/consumer set. In terms of
GraphicBuffer's relationship with BufferHub, there are three different
modes:
1. Legacy mode: GraphicBuffer is not backed by BufferHub and
mDetachedBufferHandle must be invalid.
2. Detached mode: GraphicBuffer is backed BufferHub, but not part of a
producer/consumer set. In this mode, mDetachedBufferHandle must be valid.
3. Attached mode: GraphicBuffer is backed BufferHub and it's part of a
producer/consumer set. In this mode, mDetachedBufferHandle must be
invalid.
Note that the DetachedBufferHandle is used as a opaque handle for
GraphicBuffer and it's not exposed to VNDK.
