camera2: Add support for secondary surface for stream
- Enhance OutputConfiguration to contain multiple surfaces for one
underlying stream.
- Create Camera3SharedOutputStream to handle streams with multiple
surfaces.
- Create Camera3StreamSplitter to handle buffer flows between camera and
multiple consumers.
Test: cts, and manually test camera preview/snapshot/recording
