Returns the system-wide unique id for this buffer
This can be useful as a cache key for associating additional objects with a given HardwareBuffer, such as associating an imported EGLImage with the target HardwareBuffer when processing a stream of buffers from ImageReader.
This can also be useful for doing cross-process buffer caching. As sending a HardwareBuffer over Binder is slower than sending a long, this can be used as reliable cache key after an initial handshake that passes the HardwareBuffers themselves to later be referred to using only the id.
