camera: Add physical camera metadata in CaptureResult
- When physical stream of a logical multi-camera is requested, HAL needs
to generate metadata for the physical cameras.
- In case no physical stream is requested for the logical multi-camera, no
capture result metadata is required for physical camera.
- Batch physical and logical metadata within one capture_result call.
Test: testLogicalCamera CTS test
