Camera: Improve monochrome camera capability support
- Add dummy CFA pattern for monochrome camera.
- Handle monochrome camera in DngCreator.
- Fix up static and dynamic metadata tags related to monochrome camera
for older version of devices.
Test: Camera CTS
Test: Capture a DNG file and inspect with LightRoom
