Camera: Switch to query function for display sync
The query function has the benefit of:
- Simpler code
- No need to use ndk, thus reduce size of cameraserver process
- Better latency compared to callbacks
The additional inflight preview buffers are still necessary so that
producer doesn't get starved.
Test: GoogleCamera app video mode preview, OpenCamera
Test: Camera CTS
